version 0.9.2
=============

- implement constructors + full 'not nil' checking
- ``restrict`` pragma + backend support
- fix closure bug finally
- fix marshal bug
- investigate nimgame bug


version 0.9.4
=============

- make 'bind' default for templates and introduce 'mixin'; 
  special rule for ``[]=``
- implicit deref for parameter matching; overloading based on 'var T'


version 0.9.X
=============

- FFI:
  * test libffi on windows
  * test: times.format with the FFI
- test&finish first class iterators:
  * nested iterators
- implement the missing features wrt inheritance
- improve the compiler as a service
- ``=`` should be overloadable; requires specialization for ``=``
- optimize genericAssign in the code generator
- better support for macros that rewrite procs
- macros need access to types and symbols (partially implemented)
- result = result shr 8 for the "system()" wrapper
- rethink the syntax/grammar:
  * parser is not strict enough with newlines
  * change comment handling in the AST


Concurrency
-----------

- shared memory heap: ``shared ref`` etc. The only hard part in the GC is to
  "stop the world". However, it may be worthwhile to generate explicit 
  (or implicit) syncGC() calls in loops. Automatic loop injection seems
  troublesome, but maybe we can come up with a simple heuristic. (All procs
  that `new` shared memory are syncGC() candidates... But then 'new' itself
  calls syncGC() so that's pointless.) Hm instead of an heuristic simply
  provide a ``syncgc`` pragma to trigger compiler injection --> more general:
  an ``injectLoop`` pragma
- 'writes: []' effect; track reads/writes for shared types
- use the effect system for static deadlock prevention and race detection


version 0.9.XX
==============

- object branch transitions can't work with the current 'reset'; add a 'reset'
  with an additional parameter --> re-evaluate this issue after constructors
  have been added
- fix destructors; don't work yet when used as expression; alternative for 
  version 1: disallow expressions yielding a type with a destructor that are
  not in a 'let/var' context  (p(a.openFile, b.openFile) makes no sense anyway)
- document nimdoc properly finally
- make 'clamp' a magic for the range stuff


Not essential for 1.0.0
=======================

- 'const' objects including case objects
- mocking support with ``tyProxy`` that does: fallback for ``.`` operator
- allow implicit forward declarations of procs via a pragma (so that the
  wrappers can deactivate it)
- implement the "snoopResult" pragma; no, make a strutils with string append
  semantics instead ...
- implement "closure tuple consists of a single 'ref'" optimization
- optimize method dispatchers
- ``with proc `+`(x, y: T): T`` for generic code
- new feature: ``distinct T with operations``
- arglist as a type (iterator chaining); variable length type lists for generics
- resizing of strings/sequences could take into account the memory that
  is allocated
- codegen should use "NIM_CAST" macro and respect aliasing rules for GCC
- implement marker procs for message passing
- activate more thread tests
- implement closures that support nesting of *procs* > 1


GC
==

- precise stack marking; embrace C++ code generation for that
- marker procs for Boehm GC
- implement 'mixed' GC mode


Optimizations
=============

- optimize 'if' with a constant condition
- escape analysis for string/seq seems to be easy to do too;
  even further write barrier specialization
- inlining of first class functions
- proc specialization in the code gen for write barrier specialization


Bugs
====

- sneaking with qualifiedLookup() is really broken!
- aporia.nim(968, 5) Error: ambiguous identifier: 'DELETE' -- 
  use a qualifier
- blocks can "export" an identifier but the CCG generates {} for them ...
- JS gen: fix exception handling
- the better scoping for locals is the wrong default for endb
