[antlr-interest] Re: "back to the future" (merged lexer / parser spec)

Ter--

How about extending the capability to grammars in multiple files? 
That is, support literals in all files, export the literal strings to
a text file (or files--one per grammar) and add a "requires" option to
the lexer.

A good implementation would require translating "!#" into "BangHash"
or something similar via table lookup, but that should be pretty easy.
 Then keyword literals could be used in tree grammars for readability.
 It would also make it more practical to keep the lexer grammar in a
separate file from the other grammars which could improve maintainability.
