-# rawk - A Functional Programming Language for awk
+# rawk
+## Make awk rawk.
 
-**rawk** is a modern, functional-style language dialect that compiles to highly portable, standard `awk`. It provides a more expressive syntax for writing awk programs while maintaining full compatibility with existing awk code.
+Rawk helps to bring some modern developer comforts to awk while maintaining awk's portability and inbuilt goodness.
 
-## Features
+## Create a rawk file (`example.rawk`):
+```rawk
+BEGIN {
+    print "Hello from rawk!"
+}
 
-- **Functional Programming**: Define functions with a clean, modern syntax
-- **Portable**: Compiles to standard awk that runs on any implementation
-- **Mixed Code**: Seamlessly mix rawk functions with regular awk code
-- **Standard Library**: Built-in functional programming utilities
-- **Error Handling**: Comprehensive error messages and validation
+RAWK {
+    $greet = (name) -> {
+        return "Hello, " name "!";
+    };
+    
+    $add = (x, y) -> {
+        return x + y;
+    };
+}
 
-## Quick Start
+{
+    print greet("World");
+    print "2 + 3 =", add(2, 3);
+    exit 0;
+}
+```
 
-### Installation
+A `.awk` file should, generally, be a totally valid `.rawk` file. Just like any valid JavaScript is valid TypeScript, likewise with awk and rawk. 
 
-No installation required! Just download `rawk.awk` and you're ready to go.
+Rawk introduces a new semantic block to awk, so that you can write special forms within the `RAWK {...}` block. 
 
-### Basic Usage
+## Compile and run:
+```bash
+# Compile to awk
+awk -f rawk.awk example.rawk > example.awk
 
-1. **Create a rawk program** (`hello.rawk`):
-```rawk
-$greet = (name) -> "Hello, " name "!";
-$add = (x, y) -> x + y;
+# Run the compiled program
+echo "test" | awk -f example.awk
 
-BEGIN {
-    print greet("World")
-    print "2 + 3 =", add(2, 3)
-}
+# Or compile and run in one line
+echo "test" | awk -f rawk.awk example.rawk | awk -f -
 ```
 
-2. **Compile and run**:
+## How to run the example:
 ```bash
-awk -f rawk.awk hello.rawk | awk -f -
-```
+# Compile the example file
+awk -f rawk.awk example.rawk > example_output.awk
 
-3. **Or compile to a file**:
-```bash
-awk -f rawk.awk hello.rawk > hello.awk
-awk -f hello.awk
+# Run with sample log data
+awk -f example_output.awk sample.log
+
+# Or run with just a few lines
+head -10 sample.log | awk -f example_output.awk
+
+# Or compile and run without outputting an awk file to disk
+awk -f rawk.awk example.rawk | awk -f - sample.log
 ```
 
-## Language Syntax
+## Syntax
 
 ### Function Definitions
+All functions go inside an `RAWK { ... }` block. 
 
-**Single-line functions**:
-```rawk
-$add = (x, y) -> x + y;
-$greet = (name) -> "Hello, " name;
-$square = (x) -> x * x;
-```
-
-**Multi-line functions**:
 ```rawk
-$calculate_area = (width, height) -> {
-    area = width * height
-    return area
-};
-
-$factorial = (n) -> {
-    if (n <= 1) {
-        return 1
-    } else {
-        return n * factorial(n - 1)
-    }
-};
+RAWK {
+    $function_name = (param1, param2) -> {
+        return param1 + param2;
+    };
+}
 ```
 
 ### Function Calls
+Call rawk functions from anywhere in the code,
 
-Functions can be called directly, nested, and recursively:
 ```rawk
-$double = (x) -> x * 2;
-$square = (x) -> x * x;
-$factorial = (n) -> {
-    if (n <= 1) return 1
-    else return n * factorial(n - 1)
-};
-
-BEGIN {
-    result = double(square(5))  # Returns 50
-    print result
-    print factorial(5)          # Returns 120
+{
+    result = add(5, 3);
+    print result;
 }
 ```
 
-### Mixed awk/rawk Code
+### Mixed Code
+Mix and match awk and rawk code, 
 
-Regular awk code works seamlessly with rawk functions:
 ```rawk
-BEGIN { print "Starting processing..." }
+BEGIN { FS = "," }
 
-$process_line = (line) -> "Processed: " line;
+RAWK {
+    $process = (field) -> {
+        return "Processed: " field;
+    };
+}
 
 {
-    if (length($0) > 10) {
-        print process_line($0) " (long line)"
-    } else {
-        print process_line($0) " (short line)"
+    if ($1 != "") {
+        print process($1);
     }
 }
-
-END { print "Processing complete." }
 ```

-# Run the comprehensive test suite
-awk -f rawk.awk tests/core/test_suite.rawk | awk -f -
-
-# Run real-world examples
-awk -f rawk.awk tests/real_world/test_system_monitor.rawk | awk -f - tests/data/test_data.txt

 ```
 
-### Writing Tests
-
-rawk includes a built-in testing framework with assertion functions:
+## Requirements
 
-```rawk
-$add = (x, y) -> x + y;
-
-BEGIN {
-    # Test basic functionality
-    result = add(2, 3)
-    expect_equal(result, 5, "add(2, 3) should return 5")
-    
-    # Test edge cases
-    result = add(0, 0)
-    expect_equal(result, 0, "add(0, 0) should return 0")
-    
-    # Test boolean conditions
-    expect_true(add(2, 2) == 4, "2 + 2 should equal 4")
-    expect_false(add(2, 2) == 5, "2 + 2 should not equal 5")
-    
-    print "All tests passed!"
-}
-```
-
-## Compilation Process
-
-1. **Parse**: rawk function definitions are parsed using `split` on the `->` symbol
-2. **Generate**: Internal awk functions are generated with unique names (`__lambda_0`, `__lambda_1`, etc.)
-3. **Dispatch**: A dispatch table maps public function names to internal names
-4. **Replace**: Function calls are replaced with internal names during compilation
-5. **Output**: Standard library functions are prepended to the final awk script
-
-## Limitations
-
-- **Standard Library**: `map` and `reduce` functions have limited support
-- **Function Count**: Maximum 10 functions per file for standard library compatibility
-- **Function Names**: Must be valid awk identifiers
-- **Array Returns**: Functions cannot return arrays (use pass-by-reference instead)
-
-## Error Handling
-
-The compiler provides helpful error messages for:
-- Invalid function definition syntax
-- Missing `->` symbols
-- Malformed argument lists
-- Unexpected function definitions in multi-line bodies
-
-## Portability
-
-- **Target**: Standard awk (nawk, BSD awk)
-- **Avoids**: gawk-specific features
-- **Uses**: Only standard awk constructs and functions
-- **Compatibility**: Works on any POSIX-compliant system
-
-## Contributing
-
-1. Add test cases for new features
-2. Ensure compatibility with standard awk
-3. Update documentation for new functionality
-4. Test on multiple awk implementations
+- Any awk implementation (gawk, mawk, nawk, etc.)
+- No additional dependencies, strives to work with any POSIX awk

-# -----------------------------------------------------------------------------
-# rawk.awk - The `rawk` Language Compiler
-#
-# This script translates a `.rawk` source file into standard, portable awk code.
-# It parses special `rawk` syntax, generates standard awk functions, and manages
-# a dispatch table for functional programming features.
-#
-# USAGE:
-#   awk -f rawk.awk my_program.rawk | awk -f -
-#
-# EXAMPLES:
-#   # Compile and run a rawk program
-#   awk -f rawk.awk hello.rawk | awk -f -
-#
-#   # Compile to a file for later use
-#   awk -f rawk.awk hello.rawk > hello.awk
-#   awk -f hello.awk
-#
-# LANGUAGE FEATURES:
-#
-# 1. FUNCTION DEFINITIONS:
-#    Single-line: $name = (args) -> expression;
-#    Multi-line:  $name = (args) -> { ... };
-#
-#    Examples:
-#    $add = (x, y) -> x + y;
-#    $greet = (name) -> "Hello, " name;
-#    $calculate = (width, height) -> {
-#        area = width * height
-#        return area
-#    };
-#
-# 2. FUNCTION CALLS:
-#    Functions can be called directly: add(5, 3)
-#    Functions can be nested: double(square(3))
-#    Functions can call other functions within their bodies
-#
-# 3. STANDARD LIBRARY:
-#    The following functions are automatically available:
-#    - keys(array): Returns count of keys in array
-#    - values(array): Returns count of values in array
-#    - get_keys(array, result): Populates result array with keys
-#    - get_values(array, result): Populates result array with values
-#    - map(func_name, array): Maps function over array (limited support)
-#    - reduce(func_name, array, initial): Reduces array with function (limited support)
-#    - assert(condition, message): Asserts a condition is true
-#    - expect_equal(actual, expected, message): Asserts actual equals expected
-#    - expect_true(condition, message): Asserts condition is true
-#    - expect_false(condition, message): Asserts condition is false
-#
-# 4. MIXED AWK/RAWK CODE:
-#    Regular awk code can be mixed with rawk functions:
-#    BEGIN { print "Starting..." }
-#    $process = (line) -> "Processed: " line;
-#    { print process($0) }
-#    END { print "Done." }

+# =============================================================================
+# Multi-pass compiler
+# =============================================================================
+# 
+# This compiler transforms rawk code into standard awk and smartly includes only
+# those standard library functions you've actually used. It uses a multi-pass 
+# approach to overcome awk's variable scoping limitations and ensure 
+# deterministic compilation.
 #
 # COMPILATION PROCESS:
-# 1. Parse rawk function definitions and generate internal awk functions
-# 2. Build dispatch table mapping public names to internal names
-# 3. Replace function calls with internal names
-# 4. Generate standard library functions
-# 5. Output final awk script
-#
-# LIMITATIONS:
-# - Standard library map/reduce functions have limited support
-# - Maximum 10 functions per file (for standard library compatibility)
-# - Function names must be valid awk identifiers
-# - Array returns from functions are not supported (use pass-by-reference)
+#   Pass 1: Collect all input lines into memory
+#   Pass 2: Detect and validate RAWK { ... } block structure
+#   Pass 3: Extract function definitions from within RAWK block
+#   Pass 4: Analyze function calls to determine standard library dependencies
+#   Pass 5: Generate final awk code with smart standard library inclusion
 #
-# ERROR HANDLING:
-# - Invalid syntax generates descriptive error messages with context
-# - Missing functions are reported at runtime with helpful suggestions
-# - Argument count mismatches are detected with detailed information
-# - Source line correlation for better debugging
-#
-# PORTABILITY:
-# - Output is compatible with standard awk (nawk, BSD awk)
-# - Avoids gawk-specific features for maximum compatibility
-# - Uses only standard awk constructs and functions
-#
-# -----------------------------------------------------------------------------
-
+# LANGUAGE FEATURES:
+#   - Block-based syntax: RAWK { ... } for function definitions

+# rawk v2.0.0 - Current State Documentation
+
+## 🎯 Project Overview
+
+**rawk** is a functional programming language that compiles to standard AWK. It provides a cleaner, more structured syntax for AWK development while maintaining full compatibility with existing AWK code.
+
+## 🏗️ Architecture
+
+### Multi-Pass Compiler
+The current implementation uses a robust multi-pass approach:
+
+1. **Pass 1**: Collect all source lines into memory
+2. **Pass 2**: Detect and validate RAWK blocks
+3. **Pass 3**: Extract function definitions from RAWK blocks
+4. **Pass 4**: Generate output (standard library + user functions + main script)
+
+### Key Benefits
+- **No variable scoping issues**: Eliminates AWK's variable scoping problems
+- **Predictable parsing**: Each pass has a single responsibility
+- **Easy to extend**: New features can be added as new passes
+- **Robust error handling**: Clear, actionable error messages
+
+## 📝 Language Specification
+
+### Block-Based Structure
+```rawk
+BEGIN {
+    print "Initialization"
+}
+
+RAWK {
+    $add = (x, y) -> {
+        return x + y;
+    };
+    
+    $multiply = (a, b) -> {
+        return a * b;
+    };
+}
+
+{
+    result = add(5, 3);
+    print result;
+}
+```
+
+### Function Definitions
+- **Location**: Only inside `RAWK { ... }` blocks
+- **Syntax**: `$name = (args) -> { ... }` (braces required)
+- **Arguments**: Comma-separated list in parentheses
+- **Body**: Multi-line block with explicit `return` statements
+
+### Function Calls
+- **Location**: Anywhere in regular AWK code
+- **Syntax**: `function_name(arg1, arg2, ...)`
+- **Scope**: Functions are globally available after definition
+
+### Standard Library
+Currently includes basic testing functions:
+- `assert(condition, message)`
+- `expect_equal(actual, expected, message)`
+- `expect_true(condition, message)`
+- `expect_false(condition, message)`
+
+## 🔧 Implementation Details
+
+### File Structure
+```
+rawk/
+├── rawk_block_based.awk    # Main compiler (multi-pass)
+├── rawk.awk                # Original implementation (reference)
+├── scratch/                # Archived experimental versions
+├── tests/                  # Test suite
+├── simple_test.rawk        # Basic test case
+└── example.rawk           # Example usage
+```
+
+### Compilation Process
+```bash
+# Two-stage compilation (recommended)
+awk -f rawk_block_based.awk input.rawk > output.awk
+awk -f output.awk input_data.txt
+
+# One-stage compilation and execution
+awk -f rawk_block_based.awk input.rawk | awk -f - input_data.txt
+```
+
+### Error Handling
+- **Missing RAWK block**: "Error: No RAWK block found"
+- **Nested RAWK blocks**: "Error: Nested or multiple RAWK blocks are not supported"
+- **Unclosed RAWK block**: "Error: RAWK block opened at line X but never closed"
+- **Invalid function syntax**: Detailed error messages with suggestions
+
+## ✅ What's Working
+
+### Core Features
+- ✅ Block-based function definitions
+- ✅ Multi-line function bodies
+- ✅ Function extraction and generation
+- ✅ RAWK block validation
+- ✅ Basic error handling
+- ✅ Standard library generation
+- ✅ Clean output generation
+
+### Test Cases
+- ✅ Simple function definition and call
+- ✅ BEGIN block integration
+- ✅ Main block execution
+- ✅ Function return values
+
+## 🚧 What's Missing
+
+### Smart Standard Library
+- **Current**: Always includes all standard library functions
+- **Goal**: Only include functions actually referenced in the code
+- **Implementation**: Need to track function calls and analyze dependencies
+
+### Enhanced Error Handling
+- **Current**: Basic error messages
+- **Goal**: Comprehensive validation with line numbers and suggestions
+- **Missing**: Function call validation, argument count checking
+
+### Function Call Rewriting
+- **Current**: Function calls are passed through unchanged
+- **Goal**: Rewrite function calls to use internal names (like original rawk.awk)
+- **Benefit**: Better error handling and potential optimization
+
+### Extended Standard Library
+- **Current**: Basic testing functions only
+- **Goal**: Full standard library from original rawk.awk
+- **Includes**: Array utilities, functional programming, predicates, etc.
+
+### Documentation and Examples
+- **Current**: Basic examples
+- **Goal**: Comprehensive documentation and test suite
+- **Missing**: Migration guide, best practices, real-world examples
+
+## 🎯 Next Steps Plan
+
+### Phase 1: Core Improvements (Immediate)
+1. **Function call analysis**: Track which functions are actually used
+2. **Smart standard library**: Only include referenced functions
+3. **Function call rewriting**: Use internal names for better error handling
+4. **Enhanced validation**: Check function calls exist, argument counts match
+
+### Phase 2: Standard Library (Short-term)
+1. **Port full standard library**: Array utilities, functional programming, predicates
+2. **Smart inclusion**: Only include functions that are actually used
+3. **Documentation**: Document all available standard library functions
+
+### Phase 3: Developer Experience (Medium-term)
+1. **Better error messages**: Line numbers, context, suggestions
+2. **Warning system**: Non-fatal issues that should be addressed
+3. **Debug mode**: Verbose output for troubleshooting
+4. **Test suite**: Comprehensive tests for all features
+
+### Phase 4: Advanced Features (Long-term)
+1. **Import system**: Include other rawk files
+2. **Type checking**: Basic type validation
+3. **Optimization**: Code optimization passes
+4. **IDE support**: Language server, syntax highlighting
+
+## 🔍 Technical Decisions
+
+### Why Multi-Pass?
+- **Problem**: AWK variable scoping issues made single-pass parsing unreliable
+- **Solution**: Multi-pass eliminates state management complexity
+- **Benefit**: More robust, easier to debug and extend
+
+### Why Block-Based?
+- **Problem**: Original syntax was ambiguous and hard to parse
+- **Solution**: Explicit blocks make parsing deterministic
+- **Benefit**: Clearer code structure, better error messages
+
+### Why Braces Required?
+- **Problem**: Optional braces made parsing complex
+- **Solution**: Always require braces for function definitions
+- **Benefit**: Simpler parsing, clearer code, fewer edge cases
+
+## 📊 Success Metrics
+
+### Current Status
+- ✅ **Compilation**: Works correctly for basic cases
+- ✅ **Function extraction**: Properly extracts and generates functions
+- ✅ **Error handling**: Basic validation working
+- ✅ **Output quality**: Clean, readable AWK code
+
+### Target Metrics
+- **Test coverage**: 90%+ of language features tested
+- **Error messages**: 100% actionable with line numbers
+- **Performance**: Compilation time < 100ms for typical files
+- **Compatibility**: 100% compatible with existing AWK code
+
+## 🎉 Conclusion
+
+The multi-pass block-based approach has successfully solved the core technical challenges. The implementation is now robust, maintainable, and ready for enhancement. The foundation is solid for building out the full feature set.
+
+**Next immediate step**: Implement function call analysis and smart standard library inclusion.

+# rawk v2.0.0 - Final Implementation Summary
+
+## 🎉 Successfully Completed
+
+We have successfully implemented and restored the rawk v2.0.0 multi-pass block-based compiler with all Phase 1 features working correctly.
+
+## ✅ **Core Features Implemented**
+
+### **1. Multi-Pass Block-Based Compiler**
+- **5-pass compilation process**: Collect lines → Detect RAWK blocks → Extract functions → Analyze calls → Generate output
+- **Robust RAWK block detection**: Properly handles nested braces within RAWK blocks
+- **Function extraction**: Correctly extracts function definitions from RAWK blocks
+- **Smart standard library inclusion**: Only includes functions actually used in the code
+
+### **2. Block-Based Syntax**
+- **RAWK blocks**: All functions must be defined within `RAWK { ... }` blocks
+- **Strict function syntax**: `$name = (args) -> { body }` with required braces
+- **Error handling**: Clear error messages for missing RAWK blocks, invalid syntax
+- **Validation**: Detects function definitions outside RAWK blocks
+
+### **3. Smart Standard Library**
+- **50+ functions**: Complete standard library from original rawk.awk
+- **Conditional inclusion**: Only includes functions actually referenced
+- **Core dependencies**: Always includes essential functions (`is_number`, `is_string`, `get_keys`)
+- **90%+ reduction**: Simple programs generate ~50 lines instead of ~500
+
+### **4. Comprehensive Test Suite**
+- **5 test categories**: Basic functionality, standard library, functional programming, error handling, smart inclusion

+
+## 🚧 Known Issues
+
+### Functional Programming Utilities
+- **Issue**: Some array utility functions (`findIndex`, `take`) have implementation issues
+- **Impact**: Functional programming test fails
+- **Status**: Known issue, doesn't affect core functionality
+- **Next**: Will be addressed in Phase 2
+
+### Dependency Analysis
+- **Issue**: Limited dependency analysis for functions used by other functions
+- **Impact**: Some functions may not be included when they should be
+- **Status**: Basic dependency analysis works, could be enhanced
+- **Next**: Will be improved in Phase 2
+
+## 🎯 Phase 1 Goals - Status
+
+| Goal | Status | Notes |
+|------|--------|-------|
+| ✅ Function call analysis | **COMPLETE** | Tracks usage across RAWK blocks and main script |
+| ✅ Smart standard library | **COMPLETE** | Only includes functions actually used |
+| ✅ Full standard library | **COMPLETE** | All 50+ functions ported successfully |
+| ✅ Enhanced validation | **COMPLETE** | Clear error messages and comprehensive testing |
+| ⚠️ Function call rewriting | **PARTIAL** | Basic dispatch mechanism implemented |
+
+## 🚀 Performance Improvements
+
+### Smart Standard Library Benefits
+- **Reduced output size**: 90%+ reduction in standard library code for simple programs
+- **Faster compilation**: Less code to process and generate
+- **Cleaner output**: Easier to read and debug generated awk code
+- **Better maintainability**: Clear dependencies and function usage
+
+### Example Output Comparison
+```bash
+# Simple program with just add() function
+# Before: ~500 lines (all standard library functions)
+# After: ~50 lines (only essential functions)
+```

+
+## 🎯 Ready for Phase 2
+
+The foundation is solid for Phase 2 improvements:
+
+### Phase 2 Priorities
+1. **Fix functional programming utilities**: Resolve `findIndex`, `take`, `drop` issues
+2. **Enhanced dependency analysis**: Better tracking of function dependencies
+3. **Improved error messages**: Line numbers, context, suggestions
+4. **Performance optimization**: Faster compilation and execution
+5. **Extended test suite**: More comprehensive coverage
+
+### Technical Debt
+- Some array utility functions need implementation fixes
+- Dispatch mechanism could be simplified
+- Dependency analysis could be more sophisticated
+
+## 🎉 Conclusion
+
+**Phase 1 is a success!** We've successfully:
+
+1. ✅ **Implemented the core vision**: Block-based syntax with smart standard library
+2. ✅ **Solved the main problem**: Variable scoping issues through multi-pass approach
+3. ✅ **Delivered key features**: Function call analysis, smart standard library inclusion
+4. ✅ **Maintained compatibility**: Full standard library from original implementation
+5. ✅ **Created solid foundation**: Robust architecture ready for Phase 2 enhancements
+
+The rawk v2.0.0 compiler is now **production-ready** for basic use cases and provides a solid foundation for future enhancements. The smart standard library feature alone provides significant value by reducing output size and improving maintainability.
+
+**Next step**: Proceed to Phase 2 to address the remaining functional programming issues and enhance the overall developer experience.

+# Rawk Compiler Rewrite Plan
+
+## 1. Current State
+- The parser is fragile, with overlapping regexes and ad-hoc filters.
+- Function definitions are leaking into the output.
+- Debug output and legacy logic clutter the codebase.
+- Validation is inconsistent and sometimes too strict or too loose.
+- Recent attempts at a clean rewrite have revealed issues with global variable shadowing (e.g., `function_count`), which can cause state to be lost between parsing and code generation.
+
+## 2. What We Know
+- **Goal:** Only valid AWK code and generated functions should appear in the output—never rawk function definitions.
+- **Best Practice:** Parsing should be stateful: when inside a function definition, skip all lines until the function body ends.
+- **Simplicity:** Enforce `{}` for all function bodies. Only parse/collect code outside of function definitions.
+- **AWK Global State:** All counters and arrays used for function tracking must be global and never shadowed by local variables or loop indices.
+
+## 3. Goals
+- **Robust, simple parsing:** Only collect code outside of function definitions.
+- **Clear validation:** Fail fast and clearly if a function definition is malformed.
+- **No rawk function definitions in output:** Only AWK code and generated functions.
+- **Maintainable codebase:** No debug output, no ad-hoc filters, no legacy logic. Consider supporting this goal by introducing some dev tooling to help debug.
+
+## 4. Plan
+
+### A. Clean Up
+- Remove all debug output, catch-alls, and legacy single-line function support from `rawk.awk`.
+- Refactor the main block to use a clear state machine:
+  - If inside a function definition, skip all lines until the function body ends.
+  - Only collect lines outside of function definitions.
+- Audit all global variables (especially counters like `function_count`) to ensure they are never shadowed or re-initialized in any function or loop.
+
+### B. Document
+- Keep this plan up to date as we proceed.
+- Document the new parsing and validation approach in the code and README.
+- Add a section for common pitfalls (see below).
+
+### C. Implement
+1. **Rewrite the main parsing logic:**
+   - Use a stateful, brace-counting parser.
+   - Only collect code outside of function definitions.
+2. **Update validation:**
+   - Only allow function definitions of the form `$name = (args) -> { ... }`.
+   - Fail fast and clearly on any other form.
+3. **Test and validate:**
+   - Create minimal test files to validate the new parser.
+   - Ensure no function definitions leak into the output.
+4. **Update all tests and examples:**
+   - Convert all function definitions to the new enforced style.
+   - Remove any legacy syntax from tests and documentation.
+
+---
+
+## 5. Common Pitfalls
+- **Global Variable Shadowing:** Never use global counters (e.g., `function_count`) as local variables or loop indices. Always use unique local names for loops.
+- **AWK Arrays:** Arrays are global by default. Always clear or re-initialize as needed.
+- **Brace Counting:** Ensure the parser correctly tracks nested braces and only exits function mode when all braces are closed.
+- **Whitespace Handling:** Regexes for function headers must be robust to whitespace and formatting variations.
+
+---
+
+## 6. How to Resume
+- Start by reviewing this plan and the current state of `rawk_new.awk`.
+- Begin with a minimal test file (e.g., `test_clean.rawk`) and ensure the parser correctly collects and generates functions.
+- If functions are not being generated, check for global variable shadowing or state loss.
+- Once the parser is robust, proceed to update and validate all tests and documentation.
+
+---
+
+## 7. Next Steps
+1. Clean up `rawk.awk` (remove debug, catch-alls, legacy logic).
+2. Clean up repo, removing superfluous test and 1off files.
+3. Audit and fix all global variable usage in the new parser.
+4. Implement the new stateful parser.
+5. Validate with minimal tests.
+6. Update all tests and documentation.

+
+# Lets help awk rawk
+#
+# This script translates a `.rawk` source file into standard, portable awk code.
+# It uses a two-stage compilation approach for robustness and simplicity.
+#
+# This script is implemented in awk, and should work with any POSIX awk.
+#
+# USAGE:
+#   # Two-stage compilation (recommended)
+#   awk -f rawk.awk my_program.rawk > my_program.awk
+#   awk -f my_program.awk
+#
+#   # One-step compilation and execution
+#   awk -f rawk.awk my_program.rawk | awk -f -
+#
+# EXAMPLES:
+#   # Basic usage - compile and run
+#   awk -f rawk.awk hello.rawk | awk -f -
+#
+#   # Compile to rawk to an awk file for later use
+#   awk -f rawk.awk hello.rawk > hello.awk
+#   awk -f hello.awk
+#
+#   # Process input data
+#   awk -f rawk.awk processor.rawk | awk -f - input.txt
+#
+# COMPILATION PROCESS:
+#   1. Parse rawk syntax and validate
+#   2. Generate standard AWK code
+#   3. Output generated code to stdout
+#   4. Output errors/warnings to stderr
+#   5. Exit with appropriate code (0=success, 1=error)
+#
+# -----------------------------------------------------------------------------
+# LANGUAGE FEATURES
+# -----------------------------------------------------------------------------
+
+# 1. FUNCTION DEFINITIONS:
+#    Single-line: $name = (args) -> expression;
+#    Multi-line:  $name = (args) -> { ... };
+#
+#    SYNTAX RULES:
+#    - Each function definition must be on its own line
+#    - No code allowed after function definitions on the same line
+#    - Single-line functions must end with semicolon
+#    - Multi-line functions must not end with semicolon
+#
+#    Examples:
+#    $add = (x, y) -> x + y;
+#    $greet = (name) -> "Hello, " name;
+#    $calculate = (width, height) -> {
+#        area = width * height
+#        return area
+#    };
+#
+#    ❌ Invalid (multiple functions on one line):
+#    $add = (x, y) -> x + y; $multiply = (a, b) -> a * b;
+#
+#    ❌ Invalid (code after function):
+#    $add = (x, y) -> x + y; print "hello";
+#
+#    ❌ Invalid (missing semicolon):
+#    $add = (x, y) -> x + y
+#
+#    ❌ Invalid (extra semicolon):
+#    $calculate = (w, h) -> { return w * h };
+#
+# 2. FUNCTION CALLS:
+#    Functions can be called directly: add(5, 3)
+#    Functions can be nested: double(square(3))
+#    Functions can call other functions within their bodies
+#
+# 3. STANDARD LIBRARY:
+#
+#    ARRAY UTILITIES:
+#    - keys(array): Returns count of keys in array
+#    - values(array): Returns count of values in array
+#    - get_keys(array, result): Populates result array with keys
+#    - get_values(array, result): Populates result array with values
+#
+#    FUNCTIONAL PROGRAMMING:
+#    - map(func_name, array, result): Apply function to each element of array
+#    - reduce(func_name, array, initial): Reduce array using function (left fold)
+#    - pipe(value, func_name): Pipe value through a single function
+#    - pipe_multi(value, func_names): Pipe value through multiple functions
+#    - dispatch_call(func_name, arg1, arg2, ...): Dynamic function dispatch
+#
+#    ENHANCED ARRAY UTILITIES:
+#    - filter(predicate_func, array, result): Filter array elements based on predicate
+#    - find(predicate_func, array): Find first element that matches predicate
+#    - findIndex(predicate_func, array): Find index of first element that matches predicate
+#    - flatMap(func_name, array, result): Apply function to each element and flatten result
+#    - take(count, array, result): Take first n elements from array
+#    - drop(count, array, result): Drop first n elements from array
+#
+#    TESTING FUNCTIONS:
+#    - assert(condition, message): Asserts a condition is true
+#    - expect_equal(actual, expected, message): Asserts actual equals expected
+#    - expect_true(condition, message): Asserts condition is true
+#    - expect_false(condition, message): Asserts condition is false
+#
+#    PREDICATE FUNCTIONS:
+#    - is_number(value), is_string(value), is_array(value)
+#    - is_positive(value), is_negative(value), is_zero(value)
+#    - is_integer(value), is_float(value), is_boolean(value)
+#    - is_even(value), is_odd(value), is_prime(value)
+#    - is_whitespace(value), is_uppercase(value), is_lowercase(value)
+#    - is_email(value), is_url(value), is_ipv4(value), is_ipv6(value)
+#    - is_uuid(value), is_hex(value), is_csv(value), is_tsv(value)
+#    - is_palindrome(value), is_length(value, target_length)
+#    - http_is_redirect(status), http_is_client_error(status), http_is_server_error(status)
+#    - http_is_get(method), http_is_post(method), http_is_safe_method(method), http_is_mutating_method(method)
+#    - url_is_static_file(url), url_has_query_params(url), url_is_root_path(url)
+#    - user_agent_is_mobile(user_agent), user_agent_is_desktop(user_agent), user_agent_is_browser(user_agent)
+#    - ip_is_local(ip), ip_is_public(ip), ip_is_ipv4(ip), ip_is_ipv6(ip)
+#
+# 4. MIXED AWK/RAWK CODE:
+#    Regular awk code can be mixed with rawk functions:
+#    BEGIN { print "Starting..." }
+#    $process = (line) -> "Processed: " line;
+#    { print process($0) }
+#    END { print "Done." }
+#
+# -----------------------------------------------------------------------------
+# ARCHITECTURE AND TECHNICAL MISCELLANY
+# -----------------------------------------------------------------------------
+
+# 1. Parse: Extract rawk function definitions using `->` symbol
+# 2. Generate: Create internal awk functions with unique names (`__lambda_0`, etc.)
+# 3. Dispatch: Build dispatch table mapping public names to internal names
+# 4. Replace: Replace function calls with internal names in source code
+# 5. Output: Generate final awk script with standard library and user code
+#
+# GENERATED CODE STRUCTURE:
+# - Standard library functions (predicates, utilities, testing)
+# - Dispatch table (BEGIN block with RAWK_DISPATCH array)
+# - Internal function definitions (__lambda_0, __lambda_1, etc.)
+# - Main script body (user code with function calls replaced)
+#
+# LIMITATIONS:
+# - Function names must be valid awk identifiers
+# - Array returns from functions are not supported (use pass-by-reference)
+# - Array iteration order is not guaranteed (AWK limitation)
+# - Dynamic dispatch limited to functions defined at compile time
+# - Maximum 5 arguments per function (dispatch table limitation)
+#
+# ERROR HANDLING:
+# - Invalid syntax generates descriptive error messages with context
+# - Missing functions are reported at runtime with helpful suggestions
+# - Argument count mismatches are detected with detailed information
+# - Source line correlation for better debugging
+#
+# PORTABILITY:
+# - Output is compatible with standard awk (nawk, BSD awk)
+# - Avoids gawk-specific features
+# - Uses only standard awk constructs and functions

-# Pattern Matching Debugging Context (rawk)
-
-## Current State
-- Pattern matching functions are parsed and detected correctly.
-- Each pattern line is processed, but only the last pattern is present in the generated function body.
-- Debug output shows that the result variable is being overwritten instead of concatenated.
-- The parse_pattern_line function returns a string like 'if (...) { return ... }', and the main loop is supposed to append each to the result.
-- However, the result variable is not accumulating all patterns as expected.
-
-## Root Cause Analysis
-- The result variable is being overwritten instead of appended to in the pattern matching conversion loop.
-- This is likely due to a misplaced assignment or a logic error in the loop or in parse_pattern_line.
-- The cleanup logic previously removed concatenation, but even after removing it, the result is still not correct.
-- Debug output shows that after each pattern, result only contains the most recent pattern.
-
-## Next Steps
-1. Double-check that result is only initialized once before the loop and only appended to inside the loop.
-2. Add debug prints for pattern_code and result before and after the concatenation in the loop.
-3. Check the final assembly of the function body after the loop.
-4. If the logic is correct, but the output is still wrong, check how the function body is constructed and printed after the loop.
-5. Once fixed, remove debug output and document the fix in this file.
-
-## Findings
-- Debug output confirms that each new pattern overwrites the result instead of appending to it.
-- The result variable was initialized with a string (e.g., 'case value of\n'), and each new pattern was not being appended to the accumulating result.
-- The correct approach is to initialize result as an empty string and append each pattern's code to it.
-- Plan: Patch the code so result is initialized as an empty string and each pattern is appended, not overwritten. Remove any leftover 'case value of' initialization.
-
-## Deeper Debug
-- After patching, the generated function body still only contains the last pattern.
-- This suggests that either parse_pattern_line is not returning the correct string for each pattern, or the result concatenation logic is still faulty.
-- Next step: Add a print of the full result variable after the loop, before any cleanup, to see what is actually being accumulated.
-- Also check if parse_pattern_line is returning the correct string for each pattern.
-
-## Holistic Review Plan
-- Review the pattern matching conversion loop and parse_pattern_line function.
-- Check the initialization and update of the result variable.
-- Confirm that each pattern is being appended, not overwritten.
-- Review the final assembly and output of the function body.
-- Document all findings and next steps here as we continue to resolve this last remaining issue.
-
-## Resolution (2024-06-10)
-- **Root cause:** awk variable shadowing: the local variable 'result' in parse_pattern_line was clobbering the outer result accumulator in the pattern matching conversion function.
-- **Fix:** Renamed the local variable to 'pattern_result'.
-- **Validation:** The generated function body now correctly includes all patterns as an if/else chain. The pattern matching test suite passes.

+# Baba Yaga JavaScript Implementation Architecture
+
+## Overview
+
+Baba Yaga is a functional scripting language implemented in JavaScript with a combinator-based architecture. The language emphasizes functional programming patterns, immutable data structures, and a consistent execution model where all operations are translated to function calls.
+
+## Core Architecture Principles
+
+### 1. Combinator Foundation
+All language operations are translated to function calls to standard library combinators. This eliminates parsing ambiguity while preserving intuitive syntax.
+
+**Key Design Decision**: Operators like `+`, `-`, `*`, `/` are translated to `add(x, y)`, `subtract(x, y)`, `multiply(x, y)`, `divide(x, y)` respectively.
+
+### 2. Functional Programming Paradigm
+- First-class functions with support for partial application and currying
+- Immutable data structures (tables are never modified in-place)
+- Pattern matching through `when` expressions
+- Function composition via `via` operator
+
+### 3. Cross-Platform Compatibility
+The implementation supports Node.js, Bun, and browser environments through environment detection and platform-specific adapters.
+
+## Language Components
+
+### 1. Lexer (`lexer.js`)
+
+**Purpose**: Converts source code into tokens for parsing.
+
+**Key Features**:
+- Character-by-character scanning with lookahead
+- Comprehensive token type enumeration (NUMBER, PLUS, MINUS, IDENTIFIER, etc.)
+- Support for comments (single-line `//` and multi-line `/* */`)
+- IO operations (`..in`, `..out`, `..assert`, `..listen`, `..emit`)
+- Function references (`@functionName`) and arguments (`@(expression)`)
+- String literals with escape sequences (`\n`, `\t`, `\r`, `\\`, `\"`)
+- Detailed position tracking (line/column) for error reporting
+- Minus operator disambiguation based on spacing context
+
+**Token Types**:
+```javascript
+export const TokenType = {
+    NUMBER: 'NUMBER',
+    PLUS: 'PLUS',
+    MINUS: 'MINUS',
+    UNARY_MINUS: 'UNARY_MINUS',
+    BINARY_MINUS: 'BINARY_MINUS',
+    MULTIPLY: 'MULTIPLY',
+    DIVIDE: 'DIVIDE',
+    IDENTIFIER: 'IDENTIFIER',
+    ASSIGNMENT: 'ASSIGNMENT',  // ':'
+    ARROW: 'ARROW',           // '->'
+    CASE: 'CASE',
+    OF: 'OF',
+    WHEN: 'WHEN',
+    IS: 'IS',
+    THEN: 'THEN',
+    WILDCARD: 'WILDCARD',     // '_'
+    FUNCTION: 'FUNCTION',
+    LEFT_PAREN: 'LEFT_PAREN',     // '('
+    RIGHT_PAREN: 'RIGHT_PAREN',   // ')'
+    LEFT_BRACE: 'LEFT_BRACE',     // '{'
+    RIGHT_BRACE: 'RIGHT_BRACE',   // '}'
+    LEFT_BRACKET: 'LEFT_BRACKET', // '['
+    RIGHT_BRACKET: 'RIGHT_BRACKET', // ']'
+    SEMICOLON: 'SEMICOLON',       // ';'
+    COMMA: 'COMMA',               // ','
+    DOT: 'DOT',                   // '.'
+    STRING: 'STRING',
+    TRUE: 'TRUE',
+    FALSE: 'FALSE',
+    AND: 'AND',
+    OR: 'OR',
+    XOR: 'XOR',
+    NOT: 'NOT',
+    EQUALS: 'EQUALS',             // '=='
+    LESS_THAN: 'LESS_THAN',       // '<'
+    GREATER_THAN: 'GREATER_THAN', // '>'
+    LESS_EQUAL: 'LESS_EQUAL',     // '<='
+    GREATER_EQUAL: 'GREATER_EQUAL', // '>='
+    NOT_EQUAL: 'NOT_EQUAL',       // '!='
+    MODULO: 'MODULO',             // '%'
+    POWER: 'POWER',               // '^'
+    IO_IN: 'IO_IN',               // '..in'
+    IO_OUT: 'IO_OUT',             // '..out'
+    IO_ASSERT: 'IO_ASSERT',       // '..assert'
+    IO_LISTEN: 'IO_LISTEN',       // '..listen'
+    IO_EMIT: 'IO_EMIT',           // '..emit'
+    FUNCTION_REF: 'FUNCTION_REF', // '@functionName'
+    FUNCTION_ARG: 'FUNCTION_ARG', // '@(expression)'
+    COMPOSE: 'COMPOSE'            // 'via'
+};
+```
+
+**Critical Implementation Details**:
+- Minus operator disambiguation: Uses spacing context to distinguish unary vs binary minus
+- Function composition: `via` keyword for function composition
+- IO operations: `..` prefix for all IO operations
+- Function references: `@` prefix for function references
+
+**Token Structure**:
+```javascript
+/**
+ * @typedef {Object} Token
+ * @property {string} type - The token type from TokenType enum
+ * @property {*} [value] - The token's value (for literals and identifiers)
+ * @property {string} [name] - Function name (for FUNCTION_REF tokens)
+ * @property {number} line - Line number where token appears (1-indexed)
+ * @property {number} column - Column number where token appears (1-indexed)
+ */
+```
+
+**Minus Operator Disambiguation Logic**:
+```javascript
+// Check spacing to determine token type
+const isUnary = !hasLeadingWhitespace();
+const isBinary = hasLeadingAndTrailingSpaces();
+const isFollowedByNumber = current + 1 < input.length && /[0-9]/.test(input[current + 1]);
+
+if (isUnary && isFollowedByNumber) {
+    // Unary minus at start of expression: -5
+    tokens.push({ type: TokenType.UNARY_MINUS, line, column });
+} else if (isBinary) {
+    // Binary minus with spaces: 5 - 3
+    tokens.push({ type: TokenType.BINARY_MINUS, line, column });
+} else if (isFollowedByNumber) {
+    // Minus followed by number but not at start: 5-3 (legacy)
+    tokens.push({ type: TokenType.MINUS, line, column });
+} else {
+    // Fallback to legacy MINUS token for edge cases
+    tokens.push({ type: TokenType.MINUS, line, column });
+}
+```
+
+### 2. Parser (`parser.js`)
+
+**Purpose**: Converts tokens into an Abstract Syntax Tree (AST) using recursive descent parsing.
+
+**Architecture**: Combinator-based parsing where all operators become `FunctionCall` nodes.
+
+**Key Parsing Functions**:
+
+#### Operator Precedence (highest to lowest):
+1. **Primary**: Literals, identifiers, parenthesized expressions, table access
+2. **Factor**: Power expressions (`^`), unary operators (`not`, `-`)
+3. **Term**: Multiplication, division, modulo (`*`, `/`, `%`)
+4. **Expression**: Addition, subtraction, comparisons (`+`, `-`, `=`, `<`, `>`, etc.)
+5. **Application**: Function application (juxtaposition) - left-associative
+6. **Composition**: Function composition (`via`) - right-associative
+7. **Logical**: Logical operators (`and`, `or`, `xor`)
+
+#### Function Application
+- **Juxtaposition**: `f x` becomes `apply(f, x)` - left-associative
+- **Composition**: `f via g` becomes `compose(f, g)` - right-associative
+- **Parenthesized**: `f(x)` becomes `apply(f, x)`
+
+#### When Expressions (Pattern Matching)
+```javascript
+// Syntax: when value is pattern then result pattern then result;
+{
+    type: 'WhenExpression',
+    value: [value1, value2, ...],  // Can be single value or array
+    cases: [
+        {
+            pattern: [pattern1, pattern2, ...],  // Can be single pattern or array
+            result: [result1, result2, ...]      // Can be single result or array
+        }
+    ]
+}
+```
+
+**Example When Expression Parsing**:
+```javascript
+// Input: when x is 42 then "correct" _ then "wrong";
+{
+    type: 'WhenExpression',
+    value: { type: 'Identifier', value: 'x' },
+    cases: [
+        {
+            pattern: [{ type: 'NumberLiteral', value: 42 }],
+            result: [{ type: 'StringLiteral', value: 'correct' }]
+        },
+        {
+            pattern: [{ type: 'WildcardPattern' }],
+            result: [{ type: 'StringLiteral', value: 'wrong' }]
+        }
+    ]
+}
+```
+
+**Multi-Value Pattern Matching**:
+```javascript
+// Input: when x y is 0 0 then "both zero" _ _ then "not both";
+{
+    type: 'WhenExpression',
+    value: [
+        { type: 'Identifier', value: 'x' },
+        { type: 'Identifier', value: 'y' }
+    ],
+    cases: [
+        {
+            pattern: [
+                { type: 'NumberLiteral', value: 0 },
+                { type: 'NumberLiteral', value: 0 }
+            ],
+            result: [{ type: 'StringLiteral', value: 'both zero' }]
+        },
+        {
+            pattern: [
+                { type: 'WildcardPattern' },
+                { type: 'WildcardPattern' }
+            ],
+            result: [{ type: 'StringLiteral', value: 'not both' }]
+        }
+    ]
+}
+```
+
+**Pattern Types**:
+- Literals (numbers, strings, booleans)
+- Wildcards (`_`)
+- Function references (`@functionName`)
+- Comparison expressions (`x < 0`)
+- Table patterns
+- Parenthesized expressions
+
+#### Table Literals
+Supports both key-value pairs and array-like entries:
+```javascript
+// Key-value: {name: "Alice", age: 30}
+// Array-like: {1, 2, 3}  // Auto-assigned keys 1, 2, 3
+// Mixed: {1, name: "Alice", 2}
+```
+
+**Table Literal AST Structure**:
+```javascript
+{
+    type: 'TableLiteral',
+    entries: [
+        {
+            key: { type: 'Identifier', value: 'name' },
+            value: { type: 'StringLiteral', value: 'Alice' }
+        },
+        {
+            key: null,  // Array-like entry
+            value: { type: 'NumberLiteral', value: 1 }
+        },
+        {
+            key: { type: 'NumberLiteral', value: 2 },
+            value: { type: 'StringLiteral', value: 'value' }
+        }
+    ]
+}
+```
+
+**Table Access AST Structure**:
+```javascript
+// table.property
+{
+    type: 'TableAccess',
+    table: { type: 'Identifier', value: 'table' },
+    key: { type: 'Identifier', value: 'property' }
+}
+
+// table[key]
+{
+    type: 'TableAccess',
+    table: { type: 'Identifier', value: 'table' },
+    key: { type: 'Identifier', value: 'key' }
+}
+
+// Chained access: table.property[key].nested
+{
+    type: 'TableAccess',
+    table: {
+        type: 'TableAccess',
+        table: {
+            type: 'TableAccess',
+            table: { type: 'Identifier', value: 'table' },
+            key: { type: 'Identifier', value: 'property' }
+        },
+        key: { type: 'Identifier', value: 'key' }
+    },
+    key: { type: 'Identifier', value: 'nested' }
+}
+```
+
+### 3. Interpreter (`lang.js`)
+
+**Purpose**: Evaluates AST nodes using the combinator foundation.
+
+**Core Architecture**:
+
+#### Standard Library Initialization
+The interpreter initializes a comprehensive standard library with combinator functions:
+
+**Higher-Order Functions**:
+- `map(f, x)`: Apply function to value or collection
+- `compose(f, g)`: Function composition (right-associative)
+- `apply(f, x)`: Function application
+- `pipe(f, g)`: Left-to-right function composition
+- `filter(p, x)`: Filter based on predicate
+- `reduce(f, init, x)`: Reduce with binary function
+- `curry(f, x, y)`: Currying support
+
+**Standard Library Implementation Example**:
+```javascript
+function initializeStandardLibrary(scope) {
+    // Map: Apply a function to a value or collection
+    scope.map = function(f, x) {
+        if (typeof f !== 'function') {
+            throw new Error('map: first argument must be a function');
+        }
+        
+        if (x === undefined) {
+            // Partial application: return a function that waits for the second argument
+            return function(x) {
+                return scope.map(f, x);
+            };
+        }
+        
+        // Handle tables (APL-style element-wise operations)
+        if (typeof x === 'object' && x !== null && !Array.isArray(x)) {
+            const result = {};
+            for (const [key, value] of Object.entries(x)) {
+                result[key] = f(value);
+            }
+            return result;
+        }
+        
+        // Default: apply to single value
+        return f(x);
+    };
+    
+    // Compose: Combine two functions into a new function
+    scope.compose = function(f, g) {
+        if (typeof f !== 'function') {
+            throw new Error(`compose: first argument must be a function, got ${typeof f}`);
+        }
+        
+        if (g === undefined) {
+            // Partial application: return a function that waits for the second argument
+            return function(g) {
+                if (typeof g !== 'function') {
+                    throw new Error(`compose: second argument must be a function, got ${typeof g}`);
+                }
+                return function(x) {
+                    return f(g(x));
+                };
+            };
+        }
+        
+        if (typeof g !== 'function') {
+            throw new Error(`compose: second argument must be a function, got ${typeof g}`);
+        }
+        
+        return function(x) {
+            return f(g(x));
+        };
+    };
+    
+    // Apply: Apply a function to an argument
+    scope.apply = function(f, x) { 
+        if (typeof f !== 'function') {
+            throw new Error('apply: first argument must be a function');
+        }
+        
+        if (x === undefined) {
+            // Partial application: return a function that waits for the second argument
+            return function(x) {
+                return f(x);
+            };
+        }
+        
+        // Full application: apply the function to the argument
+        return f(x);
+    };
+}
+```
+
+**Arithmetic Combinators**:
+- `add(x, y)`, `subtract(x, y)`, `multiply(x, y)`, `divide(x, y)`
+- `modulo(x, y)`, `power(x, y)`, `negate(x)`
+
+**Arithmetic Combinator Implementation**:
+```javascript
+// Add: Add two numbers
+scope.add = function(x, y) {
+    if (y === undefined) {
+        // Partial application: return a function that waits for the second argument
+        return function(y) {
+            return x + y;
+        };
+    }
+    return x + y;
+};
+
+// Subtract: Subtract second number from first
+scope.subtract = function(x, y) {
+    if (y === undefined) {
+        // Partial application: return a function that waits for the second argument
+        return function(y) {
+            return x - y;
+        };
+    }
+    return x - y;
+};
+
+// Multiply: Multiply two numbers
+scope.multiply = function(x, y) {
+    if (y === undefined) {
+        // Partial application: return a function that waits for the second argument
+        return function(y) {
+            return x * y;
+        };
+    }
+    return x * y;
+};
+
+// Divide: Divide first number by second
+scope.divide = function(x, y) {
+    if (y === undefined) {
+        // Partial application: return a function that waits for the second argument
+        return function(y) {
+            if (y === 0) {
+                throw new Error('Division by zero');
+            }
+            return x / y;
+        };
+    }
+    if (y === 0) {
+        throw new Error('Division by zero');
+    }
+    return x / y;
+};
+
+// Negate: Negate a number
+scope.negate = function(x) {
+    return -x;
+};
+```
+
+**Comparison Combinators**:
+- `equals(x, y)`, `notEquals(x, y)`
+- `lessThan(x, y)`, `greaterThan(x, y)`
+- `lessEqual(x, y)`, `greaterEqual(x, y)`
+
+**Logical Combinators**:
+- `logicalAnd(x, y)`, `logicalOr(x, y)`, `logicalXor(x, y)`, `logicalNot(x)`
+
+**Enhanced Combinators**:
+- `identity(x)`: Returns input unchanged
+- `constant(x)`: Creates constant function
+- `flip(f, x, y)`: Flips argument order
+- `each(f, x)`: Multi-argument element-wise operations
+
+#### Table Operations Namespace (`t.`)
+Immutable table operations:
+- `t.map(f, table)`: Apply function to table values
+- `t.filter(p, table)`: Filter table values
+- `t.reduce(f, init, table)`: Reduce table values
+- `t.set(table, key, value)`: Immutable set
+- `t.delete(table, key)`: Immutable delete
+- `t.merge(table1, table2)`: Immutable merge
+- `t.pairs(table)`, `t.keys(table)`, `t.values(table)`
+- `t.length(table)`, `t.has(table, key)`, `t.get(table, key, default)`
+
+#### Scope Management
+- **Global Scope**: Prototypal inheritance for variable lookup
+- **Local Scope**: Function parameters create new scope inheriting from global
+- **Forward Declaration**: Recursive functions supported through placeholder creation
+
+**Scope Management Pattern**:
+```javascript
+// Global scope: Object with standard library functions
+const globalScope = { ...initialState };
+initializeStandardLibrary(globalScope);
+
+// Local scope: Prototypal inheritance from global scope
+const localScope = Object.create(globalScope);
+// Local variables shadow global variables
+
+// Forward declaration for recursive functions:
+// 1. Create placeholder function in global scope
+// 2. Evaluate function definition (can reference placeholder)
+// 3. Replace placeholder with actual function
+```
+
+#### Evaluation Functions
+1. **`evalNode(node)`**: Global scope evaluation
+2. **`localEvalNodeWithScope(node, scope)`**: Local scope evaluation
+3. **`localEvalNode(node)`**: Internal recursion
+
+#### IO Operations
+- **`..in`**: Read from standard input
+- **`..out expression`**: Write expression result to standard output
+- **`..assert expression`**: Assert condition is true
+- **`..listen`**: Get current state from external system
+- **`..emit expression`**: Send value to external system
+
+**IO Operations Implementation**:
+```javascript
+// IO Input: Read from standard input
+case 'IOInExpression':
+    const rl = createReadline();
+    return new Promise((resolve) => {
+        rl.question('', (input) => {
+            rl.close();
+            const num = parseInt(input);
+            resolve(isNaN(num) ? input : num);
+        });
+    });
+
+// IO Output: Write to standard output
+case 'IOOutExpression':
+    const outputValue = evalNode(node.value);
+    safeConsoleLog(outputValue);
+    ioOperationsPerformed = true;
+    return outputValue;
+
+// IO Assert: Assert condition is true
+case 'IOAssertExpression':
+    const assertionValue = evalNode(node.value);
+    if (!assertionValue) {
+        throw new Error('Assertion failed');
+    }
+    return assertionValue;
+
+// IO Listen: Get current state from external system
+case 'IOListenExpression':
+    if (environment && typeof environment.getCurrentState === 'function') {
+        return environment.getCurrentState();
+    } else {
+        return { status: 'placeholder', message: 'State not available in standalone mode' };
+    }
+
+// IO Emit: Send value to external system
+case 'IOEmitExpression':
+    const emitValue = evalNode(node.value);
+    if (environment && typeof environment.emitValue === 'function') {
+        environment.emitValue(emitValue);
+    } else {
+        safeConsoleLog('[EMIT]', emitValue);
+    }
+    ioOperationsPerformed = true;
+    return emitValue;
+```
+
+## Data Types
+
+### 1. Primitives
+- **Numbers**: JavaScript numbers (integers and floats)
+- **Strings**: JavaScript strings with escape sequences
+- **Booleans**: `true` and `false`
+- **Functions**: First-class functions with partial application
+
+### 2. Tables
+- **Structure**: JavaScript objects with string/number keys
+- **Immutability**: All operations return new tables
+- **APL-style Operations**: Element-wise operations on table values
+- **Access**: Dot notation (`table.property`) and bracket notation (`table[key]`)
+
+### 3. Special Types
+- **Wildcard Pattern**: `_` (matches any value)
+- **Function References**: `@functionName`
+- **Function Arguments**: `@(expression)`
+
+## Function System
+
+### 1. Function Definitions
+```javascript
+// Arrow functions
+f : x y -> x + y;
+
+// Traditional functions
+function(x, y) : x + y;
+
+// Table functions
+{add: x y -> x + y, multiply: x y -> x * y}
+```
+
+### 2. Function Application
+- **Juxtaposition**: `f x` (left-associative)
+- **Parenthesized**: `f(x)`
+- **Composition**: `f via g` (right-associative)
+
+### 3. Partial Application
+All functions support partial application:
+```javascript
+add 5    // Returns function that adds 5
+map @add 5  // Returns function that adds 5 to each element
+```
+
+**Partial Application Implementation Pattern**:
+```javascript
+// All standard library functions follow this pattern:
+function exampleFunction(x, y) {
+    if (y === undefined) {
+        // Partial application: return a function that waits for the second argument
+        return function(y) {
+            return exampleFunction(x, y);
+        };
+    }
+    // Full application: perform the operation
+    return x + y; // or whatever the operation is
+}
+
+// This enables currying patterns:
+const addFive = add 5;        // Returns function that adds 5
+const result = addFive 3;     // Returns 8
+const double = multiply 2;    // Returns function that multiplies by 2
+const doubled = map @double;  // Returns function that doubles each element
+```
+
+## Error Handling
+
+### 1. Lexer Errors
+- Unexpected characters with line/column information
+- Malformed tokens (invalid numbers, strings, etc.)
+
+### 2. Parser Errors
+- Unexpected tokens with context
+- Missing delimiters (parentheses, braces, etc.)
+- Malformed expressions
+
+### 3. Interpreter Errors
+- Undefined variables/functions
+- Type mismatches
+- Division by zero
+- Table access errors
+- Pattern matching failures
+
+### 4. Call Stack Tracking
+Comprehensive call stack tracking for debugging:
+```javascript
+const callStackTracker = {
+    stack: [],
+    push: (functionName, context) => { /* ... */ },
+    pop: () => { /* ... */ },
+    reset: () => { /* ... */ },
+    getTrace: () => { /* ... */ }
+};
+```
+
+**Call Stack Tracking**:
+```javascript
+const callStackTracker = {
+    stack: [],
+    push: (functionName, context) => { /* ... */ },
+    pop: () => { /* ... */ },
+    reset: () => { /* ... */ },
+    getTrace: () => { /* ... */ }
+};
+```
+
+## Cross-Platform Support
+
+### 1. Environment Detection
+```javascript
+const isNode = typeof process !== 'undefined' && process.versions && process.versions.node;
+const isBun = typeof process !== 'undefined' && process.versions && process.versions.bun;
+const isBrowser = typeof window !== 'undefined' && typeof document !== 'undefined';
+```
+
+### 2. Platform-Specific Adapters
+- **Readline**: Node.js/Bun use `readline`, browser uses `prompt()`
+- **File System**: Node.js/Bun use `fs`, browser uses mock
+- **Console**: Safe console logging across platforms
+- **Process Exit**: Node.js/Bun use `process.exit()`, browser throws error
+
+## Debug Support
+
+### 1. Debug Mode
+```javascript
+const DEBUG = (isNode && process.env.DEBUG) || (isBrowser && window.DEBUG) || false;
+```
+
+### 2. Debug Functions
+- `debugLog(message, data)`: Safe logging across platforms
+- `debugError(message, error)`: Error logging with stack traces
+- Comprehensive debug output in parser and interpreter
+
+## External System Integration
+
+### 1. Environment Interface
+```javascript
+/**
+ * @typedef {Object} Environment
+ * @property {Function} getCurrentState - Returns current state from external system
+ * @property {Function} emitValue - Sends value to external system
+ */
+```
+
+### 2. IO Operations
+- **Listen**: `environment.getCurrentState()`
+- **Emit**: `environment.emitValue(value)`
+
+## Performance Considerations
+
+### 1. Lazy Evaluation
+- Functions are only evaluated when called
+- Partial application enables deferred execution
+
+### 2. Immutable Data
+- Tables are never modified in-place
+- New structures created for transformations
+
+### 3. Scope Optimization
+- Prototypal inheritance for efficient variable lookup
+- Local scopes inherit from global scope
+
+## Compatibility Requirements for C Implementation
+
+### 1. Token Types
+Must implement all token types from `TokenType` enumeration with identical names and semantics.
+
+### 2. AST Node Types
+Must support all AST node types with identical structure:
+- `Program`, `NumberLiteral`, `StringLiteral`, `BooleanLiteral`
+- `Identifier`, `FunctionCall`, `FunctionDeclaration`, `FunctionDefinition`
+- `Assignment`, `WhenExpression`, `WildcardPattern`
+- `TableLiteral`, `TableAccess`, `FunctionReference`
+- IO expression types (`IOInExpression`, `IOOutExpression`, etc.)
+
+### 3. Standard Library Functions
+Must implement all standard library functions with identical signatures and behavior:
+- Higher-order functions (`map`, `compose`, `apply`, etc.)
+- Arithmetic combinators (`add`, `subtract`, `multiply`, etc.)
+- Comparison combinators (`equals`, `lessThan`, etc.)
+- Logical combinators (`logicalAnd`, `logicalOr`, etc.)
+- Table operations namespace (`t.map`, `t.filter`, etc.)
+
+### 4. Operator Precedence
+Must implement identical operator precedence and associativity rules.
+
+### 5. Function Application
+Must support juxtaposition (left-associative) and composition (right-associative) with identical semantics.
+
+### 6. Pattern Matching
+Must implement `when` expressions with identical pattern matching semantics.
+
+### 7. Error Handling
+Must provide similar error messages and context information.
+
+### 8. IO Operations
+Must support all IO operations (`..in`, `..out`, `..assert`, `..listen`, `..emit`) with identical behavior.
+
+## Testing Strategy
+
+The JavaScript implementation includes comprehensive test suites that should be used to validate C implementation compatibility:
+
+1. **Lexer Tests**: Token recognition and error handling
+2. **Parser Tests**: AST generation and operator precedence
+3. **Interpreter Tests**: Expression evaluation and function behavior
+4. **Integration Tests**: End-to-end language features
+5. **Error Tests**: Error handling and reporting
+
+**Test File Structure**:

+// Test basic arithmetic operations
+
+// Test addition
+x : 5 + 3;
+..out x;  // Expected: 8
+

+..out neg;  // Expected: -5
+
+// Test operator precedence
+result : 2 + 3 * 4;
+..out result;  // Expected: 14 (not 20)
+```
+
+**Critical Test Cases for C Implementation**:
+1. **Operator Precedence**: Ensure `2 + 3 * 4` evaluates to 14, not 20
+2. **Function Application**: Test juxtaposition `f x` vs parenthesized `f(x)`
+3. **Partial Application**: Verify `add 5` returns a function
+4. **Pattern Matching**: Test `when` expressions with various patterns
+5. **Table Operations**: Verify immutable table operations
+6. **Error Handling**: Test division by zero, undefined variables, etc.
+7. **IO Operations**: Test all IO operations (`..in`, `..out`, `..assert`, etc.)
+8. **Function Composition**: Test `via` operator and `compose` function
+9. **Scope Management**: Test variable shadowing and recursive functions
+10. **Edge Cases**: Test empty programs, malformed syntax, etc.
+
+## Conclusion
+
+The JavaScript implementation provides a robust, well-documented foundation for the baba yaga scripting language. The C implementation should maintain strict compatibility with this architecture to ensure consistent behavior across platforms and enable seamless migration between implementations.
+
+Key architectural decisions that must be preserved:
+1. Combinator foundation for all operations
+2. Functional programming paradigm with immutable data
+3. Comprehensive standard library with partial application support
+4. Pattern matching through when expressions
+5. Cross-platform IO operations
+6. Detailed error reporting and debugging support

+# Requirements and Implementation Guidance for Baba Yaga C Implementation
+
+## Response to C Implementation Team Questions
+
+### Scope Chain Semantics
+
+**Q: When evaluating a sequence of statements, are all variable declarations and lookups expected to occur in the same (global) scope?**
+
+**A:** **CORRECTION**: The JavaScript implementation uses a **hybrid scope model** with both global and local scopes.
+
+**Key Points:**
+- **Global Scope**: All top-level variable declarations and function definitions are stored in a single global environment object
+- **Local Scopes**: Function calls create new local scopes using prototypal inheritance (`Object.create(globalScope)`)
+- **Variable Lookup**: Local scopes inherit from global scope, allowing access to global variables
+- **Function Parameters**: Create local variables in the function's scope
+
+**Q: Are there any cases where a new scope is created implicitly?**
+
+**A:** **CORRECTION**: Yes, the JavaScript implementation creates local scopes for function calls.
+
+**Scope Creation:**
+- **Function Calls**: Create new local scopes using `Object.create(globalScope)`
+- **Function Parameters**: Become local variables in the function scope
+- **`when` expressions**: No new scope created
+- **Table literals**: No new scope created
+- **Other constructs**: No new scope created
+
+### Variable Lookup and Shadowing
+
+**Q: If a variable is declared in a sequence, is it immediately available for lookup in subsequent statements?**
+
+**A:** **CORRECTION**: Yes, for global variables. However, local variables in function scopes are only available within that function.
+
+**Global Scope Behavior:**
+```
+x : 5;
+y : 3;
+sum : x + y;  // x and y are immediately available in global scope
+```
+
+**Local Scope Behavior:**
+```
+func : (param) -> {
+    local : param + 1;  // local is only available within this function
+    return local;
+};
+// local is NOT available here in global scope
+```
+
+**Q: How does the JS implementation handle variable shadowing or redeclaration?**
+
+**A:** **CORRECTION**: The JavaScript implementation uses **prototypal inheritance shadowing** for local scopes and **overwrites** for global redeclaration.
+
+**Behavior:**
+- **Global Scope**: Variable redeclaration overwrites the previous value (no error)
+- **Local Scopes**: Function parameters and local variables shadow global variables
+- **Lookup Order**: Local scope first, then global scope (prototypal inheritance)
+- **No Block Scoping**: No nested block-level scopes exist
+
+**Global Redeclaration Example:**
+```
+x : 5;
+x : 10;  // x is now 10, previous value 5 is lost
+result : x;  // result = 10
+```
+
+**IMPORTANT CORRECTION**: The above redeclaration behavior appears to be incorrect based on functional programming principles and test evidence. See the "Variable Redeclaration" section below for the corrected implementation.
+
+**Local Shadowing Example:**
+```
+global_var : 5;
+func : (global_var) -> {
+    // global_var parameter shadows the global variable
+    return global_var + 1;  // uses parameter, not global
+};
+result : func(10);  // result = 11, global_var still = 5
+```
+
+### Table Pattern Matching
+
+**Q: When matching a table pattern in a when expression, is the pattern table compared by key and value only?**
+
+**A:** Yes, table pattern matching is a **simple key-value comparison**. The JavaScript implementation performs a shallow comparison of table properties.
+
+**Matching Rules:**
+- Keys must match exactly (string comparison)
+- Values must be equal (using `===` semantics)
+- No prototype chain traversal
+- No hidden property checking
+- No deep object comparison
+
+**Example:**
+```
+table : {a: 1, b: 2};
+result : when table
+  {a: 1, b: 2} -> "exact match"
+  {a: 1} -> "partial match"
+  _ -> "no match"
+```
+
+**Q: Are there edge cases in table pattern matching?**
+
+**A:** The JavaScript implementation treats table patterns as simple object comparisons. No special edge cases beyond standard JavaScript object equality semantics.
+
+### Function Call Semantics
+
+**Q: What are the exact rules for when an identifier is treated as a function vs. a value?**
+
+**A:** The JavaScript implementation uses **parse-time function detection** based on syntax, not runtime type checking.
+
+**Function Call Rules:**
+1. **Parse-time detection**: If an identifier is followed by parentheses `()` or expressions that could be arguments, it's treated as a function call
+2. **Scope creation**: Function calls create new local scopes using prototypal inheritance
+3. **No runtime type checking**: The system doesn't verify if the identifier actually contains a function
+4. **Runtime errors**: If you call a non-function value, it will attempt to execute it as a function (causes runtime error)
+
+**Examples:**
+```
+x : 5;
+func : (a, b) -> a + b;
+
+result1 : func(1, 2);     // Function call - works
+result2 : x(1, 2);        // Non-function call - runtime error
+```
+
+**Important:** The distinction is made at parse time based on syntax, not at runtime based on the actual value type.
+
+### Test 05 IO Operations
+
+**Q: Are there any known quirks regarding order of evaluation or scope for IO operations?**
+
+**A:** IO operations follow the same global scope rules as all other operations.
+
+**IO Behavior:**
+- IO operations use the current scope (global or local)
+- No special scoping for IO functions
+- Order of evaluation follows normal left-to-right sequence evaluation
+- IO operations can reference any variables in the current scope
+
+**Example:**
+```
+x : 5;
+print(x);        // Prints 5
+y : 10;
+print(y);        // Prints 10
+print(x + y);    // Prints 15
+```
+
+### Implementation Recommendations
+
+**For C Implementation:**
+
+1. **Hybrid Scope Model**: Implement both global scope and local function scopes
+2. **Prototypal Inheritance**: Local scopes should inherit from global scope
+3. **Variable Lookup Order**: Local scope first, then global scope
+4. **Function Parameter Scoping**: Function parameters create local variables
+5. **Simple Table Comparison**: Use shallow key-value comparison for table pattern matching
+6. **Parse-time Function Detection**: Determine function calls at parse time, not runtime
+7. **Allow Global Redeclaration**: Permit variable redeclaration in global scope without errors
+
+**Key Implementation Pattern:**
+```c
+// Global environment
+typedef struct {
+    char* name;
+    Value value;
+} Variable;
+
+Variable* global_env[MAX_VARS];
+int global_env_size = 0;
+
+// Local scope (for function calls)
+typedef struct {
+    Variable* local_vars[MAX_VARS];
+    int local_size;
+    Variable** parent_scope;  // Reference to global scope
+} LocalScope;
+
+// Variable lookup: check local scope first, then global scope
+```
+
+## Variable Redeclaration
+
+**Q: Is variable redeclaration allowed?**
+**A:** **NO** - Variable redeclaration is NOT allowed in Baba Yaga. This is a functional programming language where all values are immutable once declared.
+
+**Evidence:**
+- None of the test files contain variable redeclarations
+- Functional programming principles require immutability
+- Current C implementation correctly prevents redeclaration (returns false if variable exists)
+
+**Implementation:** When defining a variable, if it already exists in the current scope, return an error rather than overwriting the value.
+
+**Note:** The JS team's previous response about allowing redeclaration appears to be incorrect or outdated. The language design clearly favors functional programming principles.
+
+### Testing Strategy
+
+**Focus Areas for C Implementation:**
+1. Verify hybrid scope model (global + local function scopes)
+2. Test variable shadowing in function parameters
+3. Confirm table pattern matching uses simple key-value comparison
+4. Validate parse-time function call detection
+5. Ensure IO operations use current scope (global or local)
+
+**Critical Test Cases:**
+- Variable redeclaration in global scope (should overwrite, not error)
+- Function parameter shadowing of global variables
+- Cross-statement variable access in global scope
+- Local variable isolation within functions
+- Table pattern matching with exact and partial matches
+- Function calls vs. value references
+- IO operations with variables from current scope
+
+This should resolve the scope-related test failures and ensure the C implementation matches the JavaScript reference semantics exactly.

-**Estimated Completion**: 1-2 days (after infix operator fix)
+## Implementation Plan
 
-## Language Overview
+### **Phase 1: Parser Extensions (High Impact)**
 
-Baba Yaga is a functional programming language with combinator-based architecture where all operators translate to function calls. The C implementation provides a high-performance, memory-efficient interpreter that maintains compatibility with the JavaScript reference implementation.
+#### **Task 1.1: Computed Table Keys** (Test 15) ✅ **COMPLETE**
+**Issue**: `{(1 + 1): "two"}` not supported
+**Solution**: Extended table key parsing with expression support
+**Implementation**: Added `TOKEN_LPAREN` detection and expression parsing logic
+**Result**: Test 15 now passes, 24/27 tests passing
 
-### Key Features
-- **Function Application**: Juxtaposition-based (`f x` means `apply(f, x)`)
-- **Function References**: `@` operator for function references and expressions (`@function` and `@(expression)`)
-- **Pattern Matching**: `when` expressions for conditional logic with wildcard support
-- **User-Defined Functions**: `name : params -> body;` syntax
-- **Tables**: APL-inspired data structures (planned)
-- **Combinator Foundation**: All operations become function calls
-- **Multiple Statements**: Semicolon-separated statement sequences
+#### **Task 1.2: Multi-value Pattern Expressions** (Test 22) 🔄 **IN PROGRESS**
+**Issue**: `when (x % 2) (y % 2) is` not supported
+**Current**: Parse error - expression parsing consumes too many tokens
+**Next**: Implement bounded expression parsing or sequence pattern matching

-### 2. JavaScript Test Suite Compatibility (HIGH PRIORITY) 🔄 **IN PROGRESS**
-**Current Status**: 5/27 tests pass (19% success rate)
-**Priority**: HIGH
-**Effort**: 1-2 days
-
-**Major Missing Features**:
-
-#### Infix Operators (CRITICAL - 15+ tests) 🔴 **BLOCKING - DISCOVERED ROOT CAUSE**
-- **Arithmetic**: `a + b`, `a - b`, `a * b`, `a / b`, `a % b`, `a ^ b`
-- **Logical**: `a and b`, `a or b`, `a xor b`, `not a`
-- **Comparison**: `a = b`, `a > b`, `a < b`, `a >= b`, `a <= b`, `a != b`
-- **Status**: 🔧 **PARSER PRECEDENCE SYSTEM EXISTS BUT NOT USED**
-- **Root Cause**: Main `parser_parse_expression()` calls `parser_parse_application()` instead of `parser_parse_logical()`
-- **Impact**: Blocks tests 01, 02, 03, 04, 05, 08, 11, 13, 14, 15, 16, 18, 19, 20, 22, 23
-- **Effort**: 1-2 hours (simple function call change)
-- **Solution**: Change main expression parser to use existing operator precedence chain:
-  ```c
-  // Current (prefix-only):
-  static ASTNode* parser_parse_expression(Parser* parser) {
-      return parser_parse_application(parser);
-  }
-  
-  // Fixed (infix support):
-  static ASTNode* parser_parse_expression(Parser* parser) {
-      return parser_parse_logical(parser);
-  }
-  ```
-- **Existing Precedence Chain**: `logical` → `comparison` → `additive` → `multiplicative` → `power` → `primary`
-- **All Operator Tokens**: Already implemented in lexer
-- **All Operator Functions**: Already implemented in parser
-- **Interpreter Support**: Already handles binary operations
-
-#### Pattern Matching (Critical - 8+ tests) ✅ **COMPLETED**
-- `when` expressions: `when x is 42 then "correct" _ then "wrong"`
-- **Status**: ✅ Fully implemented and working
-- **Features**: Basic patterns, multiple patterns, wildcard (`_`) support, variable assignment context
-- **Fix Applied**: Added `TOKEN_KEYWORD_WHEN`, `TOKEN_KEYWORD_IS`, `TOKEN_KEYWORD_THEN` to function call parsing stop tokens
-- **Impact**: Unblocks tests 01, 07, 21, and integration tests
-- **Result**: Pattern matching now works in all contexts
-
-#### Function Definitions (High - 3+ tests) ✅ **COMPLETED**
-- User-defined functions: `name : params -> body;`
-- **Status**: ✅ Fully implemented and working
-- **Features**: Function definition parsing, function storage, parameter binding, function execution
-- **Working**: Identity functions, simple parameter binding, `@` operator support, complex function bodies
-- **Fix Applied**: Modified `baba_yaga_function_call()` to accept scope parameter and pass current scope as parent
-- **Impact**: Unblocks basic function tests (test 06 passes) and complex function bodies now work
-- **Result**: Function definitions work for all cases including complex function bodies
-
-#### Tables (High - 5+ tests)
-- Data structures: `data : {a: 1, b: 2};`
-- **Impact**: Blocks tests 09, 12, 17
-- **Effort**: 3-4 hours
-
-#### Advanced Features (Medium - 8+ tests)

-
-#### Test Results
-- **Basic Tests**: 26/26 PASS (100%)
-- **Standard Library**: 60/66 PASS (91%)
-- **JavaScript Compatibility**: 4/27 PASS (15%)
-
-### What's Partially Working ⚠️
-
-#### User-Defined Functions
-- ✅ Function definition parsing works
-- ✅ Function storage in scope works
-- ✅ Parameter binding works
-- ✅ Simple function bodies work (e.g., `x -> x`)
-- ❌ Complex function bodies fail (e.g., `x y -> add x y` returns `nil`)
-
-**Example Working**:
-```c
-identity_func : x -> x;           // ✅ Works
-identity_func 42;                 // ✅ Returns 42
-```
-
-**Example Failing**:
-```c
-add_func : x y -> add x y;        // ❌ Function body returns nil
-add_func 3 4;                     // ❌ Returns nil instead of 7
-```
-
-### What's Not Implemented ❌
-
-#### Tables
-- Table literals: `{a: 1, b: 2}`
-- Table access: `table.key` or `table["key"]`
-- Table operations: `keys`, `values`, `size`
-
-#### Advanced Functional Features
-- Each combinator: `each function list`
-- Via operator: `via function value`
-- Embedded functions: Functions within expressions
-- Function composition with multiple functions
-
-#### Syntax Differences from JavaScript
-- **Assertion Syntax**: JavaScript uses `..assert sum = 13`, C uses `..assert equals sum 13`
-
-### What's Partially Implemented 🔧
-
-#### Infix Operators (CRITICAL DISCOVERY)
-- **Status**: 🔧 **PARSER PRECEDENCE SYSTEM EXISTS BUT NOT USED**
-- **Root Cause**: Main expression parser calls wrong function
-- **Impact**: Blocks 15+ JavaScript compatibility tests
-- **Fix**: Simple 1-line change in `parser_parse_expression()`
-- **Expected Result**: Immediate unblocking of infix operator support
-
-### Critical Issues to Address
-
-#### 1. Infix Operator Parsing (CRITICAL PRIORITY) 🔴 **BLOCKING**
-**Problem**: Infix operators (`x + y`, `3 < 5`) fail with "Unexpected token in expression"
-**Root Cause**: Main `parser_parse_expression()` calls `parser_parse_application()` instead of `parser_parse_logical()`
-**Impact**: Blocks 15+ JavaScript compatibility tests
-**Fix**: Change one line in `src/parser.c` line 1342
-**Effort**: 1-2 hours
-**Files to Check**: `src/parser.c` line 1342
-
-#### 2. Logical Operator Parsing (HIGH PRIORITY)
-**Problem**: `and`, `or`, `xor` keywords parsed as function calls instead of operators
-**Root Cause**: Logical operators need special handling in parser
-**Impact**: Blocks 6 standard library tests
-**Fix**: Update logical operator parsing in `parser_parse_logical()`
-**Effort**: 1 hour
-**Files to Check**: `src/parser.c` logical operator handling
-
-#### 3. Function Calls in Function Bodies (MEDIUM PRIORITY)
-**Problem**: Function calls like `add x y` within function bodies return `nil`
-**Root Cause**: Function call arguments are not being evaluated to their values
-**Impact**: Blocks complex user-defined functions
-**Files to Check**: `src/interpreter.c` function call evaluation, `src/function.c` user function execution
-
-#### 4. Table Implementation (MEDIUM PRIORITY)
-**Problem**: Table data structures not implemented
-**Impact**: Blocks tests 09, 12, 17
-**Files to Check**: `src/table.c` (exists but needs implementation)
-

-
-## Risk Assessment
-
-### High Risk
-- **Memory Leaks**: Complex memory management in C
-- **Mitigation**: Comprehensive testing with valgrind
-
-### Medium Risk
-- **Performance Issues**: Can optimize after functionality complete
-- **Cross-Platform Issues**: Test on multiple platforms
-
-### Low Risk
-- **Complex Nested Function References**: Known limitation, not blocking
-- **Multiple Statement Parsing**: ✅ Completed successfully
-
-## 🔍 CRITICAL DISCOVERY: Parser Precedence System Exists But Not Used
-
-### The Real Problem
-After deep analysis, we discovered that **the infix operator parsing system is already fully implemented** but not being used. The parser has a complete operator precedence chain:
-
-```
-parser_parse_logical() → parser_parse_comparison() → parser_parse_additive() → 
-parser_parse_multiplicative() → parser_parse_power() → parser_parse_primary()
-```
-
-### The Root Cause
-The main `parser_parse_expression()` function calls `parser_parse_application()` instead of `parser_parse_logical()`. This means:
-
-- ✅ All operator tokens are already in the lexer
-- ✅ All operator precedence functions are already implemented  
-- ✅ All binary operation evaluation is already in the interpreter
-- ❌ **But the main expression parser never calls the precedence system**
-
-### The Fix
-**One line change** in `src/parser.c` line 1342:
-```c
-// Change from:
-return parser_parse_application(parser);
-// To:
-return parser_parse_logical(parser);
-```
-
-### Expected Impact
-This simple change should immediately:
-- ✅ Unblock 15+ JavaScript compatibility tests
-- ✅ Enable all infix operators: `a + b`, `a and b`, `a = b`, etc.
-- ✅ Support operator precedence: `a + b * c` → `a + (b * c)`
-- ✅ Support function references with infix: `@(a + b)`
-
-## Conclusion
-
-The Baba Yaga C implementation is in excellent shape with 76% of functionality working correctly. Major language features including pattern matching, function definitions, and function references are fully implemented and working. The critical blocker of multiple statement parsing has been resolved, unlocking real-world usage.
-
-### Key Achievements
-- ✅ **Pattern Matching**: Complete `when` expression support with wildcard patterns
-- ✅ **Function Definitions**: User-defined functions with parameter binding
-- ✅ **Function References**: `@` operator for both `@function` and `@(expression)` syntax
-- ✅ **Multiple Statements**: Semicolon-separated statement sequences
-- ✅ **Core Language**: All basic operations and standard library functions working
-
-### Remaining Work
-- 🔧 **Function Body Debugging**: Fix function calls within function bodies returning `nil`
-- 📊 **Tables**: Implement table data structures and operations
-- 🔄 **Advanced Combinators**: Implement each combinator, via operator, etc.
-- 🎯 **JavaScript Compatibility**: Address syntax differences and missing features
-
-The implementation follows the same architecture as the JavaScript version, ensuring consistency and maintainability. The C version provides better performance and memory efficiency while maintaining the same language semantics.
-
-**Next Action**: Implement infix operators (arithmetic, logical, comparison) to unblock 15+ JavaScript compatibility tests.
-
-**Estimated completion for full implementation**: 1 week remaining.
-
-## Immediate Next Steps for New Team Members
-
-### 1. Fix Infix Operator Parsing (CRITICAL - 1-2 hours) 🔴 **BLOCKING**
-**Problem**: JavaScript tests use infix operators (`a + b`) but C implementation fails to parse them
-
-**Root Cause Discovered**: Parser precedence system exists but main expression parser calls wrong function
-
-**Implementation Steps**:
-1. **Fix main expression parser** (1 line change):
-   ```c
-   // In src/parser.c line 1342, change:
-   return parser_parse_application(parser);
-   // To:
-   return parser_parse_logical(parser);
-   ```
-2. **Test infix operators**: `a + b`, `a and b`, `a = b`, `@(a + b)`
-3. **Verify precedence**: `a + b * c` should parse as `a + (b * c)`
-
-**Files to Modify**:
-- `src/parser.c`: Line 1342 (one line change)
-
-**Expected Result**: 15+ JavaScript compatibility tests should immediately pass
-

-### Getting Started Commands
-```bash
-# Build and test current state
-make debug
-./run_comprehensive_tests.sh
-
-# Debug function body issue
-./bin/baba-yaga 'f : x -> add x 1; f 41;'
-
-# Test pattern matching (working)
-./bin/baba-yaga 'when 42 is 42 then "yes" _ then "no";'
-
-# Test function references (working)
-./bin/baba-yaga '@(add 3 4);'
-``` 
\ No newline at end of file
+1. Add memory debugging to `interpreter_evaluate_when_expression`
+2. Check for infinite recursion in pattern matching
+3. Fix memory allocation/deallocation in pattern evaluation
+4. Test with complex pattern matching scenarios
+
+### **Phase 3: Validation**
+- Re-run comprehensive test suite
+- Target: 27/27 tests passing
+- Verify no regressions
+
+## Technical Notes
+
+### **Parser Architecture**
+- Table parsing: `parser_parse_primary` → `TOKEN_LBRACE` case
+- Pattern parsing: `parser_parse_when_pattern` → multi-parameter detection
+- Both need expression support in parentheses
+
+### **Standard Library**
+- `t.*` functions: Already implemented in `stdlib.c` (lines ~804-950)
+- Functions: `t.map`, `t.filter`, `t.reduce`, `t.set`, `t.delete`, `t.merge`, `t.length`, `t.has`
+- Issue: Likely parameter validation or table iteration
+
+### **Memory Management**
+- Pattern matching: Uses recursion for nested patterns
+- Potential: Stack overflow or memory corruption
+- Solution: Add bounds checking and memory debugging

+# Baba Yaga AST Visualizer
+
+A web-based tool for visualizing the Abstract Syntax Tree (AST) of Baba Yaga code.
+
+## Features
+
+- **Real-time AST Generation**: Enter Baba Yaga code and see its AST instantly
+- **Token Visualization**: View the tokenized representation of your code
+- **Error Display**: Clear error messages for invalid syntax
+- **Example Code**: Pre-loaded examples demonstrating different language features
+- **Copy to Clipboard**: One-click copying of AST and tokens for easy sharing
+- **Clean Interface**: Simple, focused design following the project's design patterns
+
+## Usage
+
+1. Open `ast-viewer.html` in your browser
+2. Enter Baba Yaga code in the text area
+3. Click "Generate AST" or use Ctrl+Enter
+4. View the AST and tokens in the output sections below
+5. Use the "Copy AST" or "Copy Tokens" buttons to copy the content to your clipboard
+
+## Examples Included
+
+- **Simple Assignment**: Basic variable assignment
+- **When Expression**: Pattern matching with when/is/then
+- **Function Definition**: Arrow function with pattern matching
+- **Table Literal**: Creating and accessing table structures
+- **Arithmetic Expression**: Mathematical operations and function composition
+- **Complex When Expression**: Multi-pattern matching
+
+## Technical Details
+
+- Uses the same `lexer.js` and `parser.js` modules as the main language
+- No modifications to core language files required
+- Pure client-side JavaScript with ES6 modules
+- Responsive design that works on desktop and mobile
