Okay, I'll bite, speaking as one who has barely dipped into those rarified waters.
Perl6 appears to solve a lot of problems inherent in Perl5's design, and introduce loads of powerful language features.
As I solve most of my practical (usually pedestrian) problems using CPAN modules, I'm unlikely to spend much time with Perl6 in the near future, however I do benefit from the cross-pollination of the two languages.
So, if you're interested in exploring the possibilities of languages and language design, Perl6 has a lot to offer. If you can map Perl6 features to your problem domain, of course it has a lot to offer.
