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.
