in reply to perl6 section on PM

I think things would be better done with a Perl 5/Perl 6 flag on the individual top-level nodes. All of the current sections are as applicable to perl 6 (or will be when it's working) as they are to perl 6, so a single "perl 6" section is likely sub-optimal, and as perl 6 gets used more it'll make it easier for individual monks to ignore the nodes for the language they're not interested in.
