Well, actually, the lexer in Perl 5 manages to be that long without ever calling back into a subparser. Everything ends up bubbling back out to the main yacc grammar, albeit highly transmogrified in the case of literal strings. How Perl 5 does two-pass string processing is one really good reason we're not doing it that way in Perl 6... :-) Larry
