    9294    - for built-in functions, have a "thisObject" accessor on List, which lazily fixes up "this", or just fix up "this" in the native function invocation code, since most native functions use "this".

    94 
    95 If a nested program overwrites the global slot holding a currently executing function, the function won't be marked during GC
    9696
    9797What things should go in dedicated local variables? CodeBlock::jsValues? CodeBlock::identifiers?
