Jeff Horwitz on mod_perl6
Though Rakudo (Perl 6 on Parrot) is still in progress, it's far enough along that you can write real Perl 6 programs that run atop mod_parrot. Jeff's slides are available as The Future of mod_perl: Perl 6 and Beyond (PDF link). This code works today, right now.
(Oh, and Rakudo is far enough along that Jeff can also show off mod_perl6 written in Perl 6.)
