Two things, one, couldn't you just make the lexer/parser in PG into a C library and then write bindings for it for use under Perl? Seems like that'd be more sane. Second, PG's got a regression test suite that would probably work decently for testing your lexer/parser. You might have to filter out '\' commands, if there are any, and things like that.
