As long as / is both "divide" and "begin regex", you're toasted. Please see my long post at "on parsing perl" in perlmonks at <http://www.perlmonks.org/index.pl?node_id=44722> for examples of *why* you need to notice whether you have a divide or a regex match. Perl is fundamentally resistant to lexing. As in the beginning of this thread, one of the RFCs suggested the possibility of making Perl lexable, but apparently the designers said "no, we think the / duality is worth keeping". And that seals the fate for Perl6 just like all Perl before it. To properly lex a Perl program (Perl6 included), you *must* execute BEGIN blocks. That's the end of that tune. Anything else is just an approximation. -- Randal L.
