/*
|
|
@! Separate out the codegen stage cause that can change
|
|
@! Change type of Stage allocator
|
|
@! Look into stage allocator and perhaps
|
|
use it more often to reduce scenarios
|
|
with 2 allocators, and simplify stuff
|
|
@! Cleanup big int allocator
|
|
@! Replace iterator interface
|
|
|
|
@! Clean way to free all memory and reset the compiler
|
|
@! Bring the Table<>
|
|
@! Look into List, check if that's neccessary
|
|
|
|
@! Compute time statistics inside context and expose them properly
|
|
|
|
Probably want to implement a Red Black Tree then
|
|
probably I wouldn't need any sort of heap based
|
|
data structure.
