If having perl documentation on PM is duplication, why is it here at all? I agree w/ Juerd that it's sometimes nice to not have to leave site site to view docs. But I do think that if we have docs here, they should be up to date. The only thing worse than no documentation is old/incorrect docs.

And 5.6.1 has been out for some time now, so it's not exactly bleeding edge anymore. 5.7.3 has that distinction now. See Perl Versions for the lowdown.
