Oh, yeah, sure -- I didn't understand what you meant.


You want a table of identifiers, so multiple occurrences are just an
index into that table or whatever. But no particular semantic
information attached to those identifiers.


I once wrote a compiler-like tool that represented identifiers
as an index into the source code. But I later decided that was
a dumb idea.
