-// Symbol table for parsing. Has these design characteristics:
-//
-// * Same symbol table can be used to compile many shaders, to preserve
-// effort of creating and loading with the large numbers of built-in
-// symbols.
-//
-// * Name mangling will be used to give each function a unique name
-// so that symbol table lookups are never ambiguous. This allows
-// a simpler symbol table structure.
-//
-// * Pushing and popping of scope, so symbol table will really be a stack
-// of symbol tables. Searched from the top, with new inserts going into
-// the top.
-//
-// * Constants: Compile time constant symbols will keep their values
-// in the symbol table. The parser can substitute constants at parse
-// time, including doing constant folding and constant propagation.
-//
-// * No temporaries: Temporaries made from operations (+, --, .xy, etc.)
-// are tracked in the intermediate representation, not the symbol table.

-FAQ, can be ftp'ed from ftp.uu.net, file usenet/net.sources/ansi.c.grammar.Z.

-possible; please let me know if you discover discrepancies.
