-# - managing tables
-# SubX has rudimentary support for tables.
-#
-# Each table is a stream of rows.
-#
-# Each row consists of a 4-byte row (address to a string) and a variable-size
-# value.
-#
-# Accessing the table performs a linear scan for a key string, and always
-# requires passing in the row size.
-#
-# Table primitives:
-#   get(stream, string, row-size)
-#     aborts if not found
-#   get-or-insert(stream, string, row-size)
-#     inserts if not found
-#   get-slice(stream, slice, row-size)
-#     aborts if not found
-#   leaky-get-or-insert-slice(stream, slice, row-size)
-#     inserts if not found
-
-# 'table' is a stream of (key, value) rows
-# keys are always strings (addresses; size 4 bytes)
-# values may be any type, but rows (key+value) always occupy 'row-size' bytes
-# scan 'table' for a row with a key 'key' and return the address of the corresponding value
-# if no row is found, abort
-get:  # table : (address stream {string, _}), key : (address string), row-size : int -> EAX : (address _)
