I haven't proposed any changes, at least not to Antlr. The support that
I've added to my parser for filenames is done without modifying Antlr at
all. (In fact, I'm using one of Ric's development snapshots - completely
unmodified. I've overridden certain parts of the library, of course.)

This is at least the second time this question of filename has come up
though. I'll see if I can do something about posting what I did to get
filename through to the AST. Won't happen right away though, I'm struggling
with cross-compilers at the moment. :-(

Yes, that's what I meant by storing an "integer index" to the filename.
