Would that be the scope thingy ? ... ILScopeLookup ?
CSCC uses a RedBlack tree for the "symbol table" .. codegen/cg_rbtree.c
should be the place to improve lookups :) .. B-Trees anyone ? ;-)
Anyway the ILScope* functions handle the scoping and lookup for CSCC.
See the ILNode_SemAnalysis(ILNode_Identifier) for a look at using ILScope.

The cs_gather.c is the Type Gathering phase when the parsed tree is
gathered and the various types collected, members constructed and
AddMemberToScope liberally used :).

The conflict between inheritance vs visitors design of the compiler
has effectively reached a truce with TreeCC . We don't need OO :)
And more often than not , it's just a matter of which language you're
comfortable with.

TreeCC ? . TreeCC has better features than C++ for building compilers.
Yes, TreeCC can output C++ , but IMHO I like the current setup better.
It's relatively straightforward to debug with gdb , it's fast enough,
builds on lotsa platforms ...

C++ -- Design for 80% of time , Implement in 20% :)
C -- Build for 80% of time , Clean up for the rest :)
