You should not be thinking about Perl6. It's deeply interesting. It's moving forward well. It's not ready. So unless it's to satisfy curiosity or to contribute or to gamble on the future to get ahead of the curve, ignore it. Perl (5) is not going to disappear. Its releases have been like clockwork for years. It's as stable and useful as any language and likely to remain the leader in things like regular expressions and Unicode support. Perl6 will have nearly zero influence on Perl5 until and if it becomes stable, complete, and as fast. This is not going to happen next year or the year after and it may never happen at all.
Perl5 is a fantastic, vibrant language, with a rich ecosphere, actively moving forward and it will be for the foreseeable future. If you like it, jump back in with both feet.
Update: did not realize I'd klept "vibrant" from Corion. :P Regarding Python: the 2/3 split being installed and competing with shoddy include/discovery code on boxes in install scripts is what led me to wonder how anyone likes it at all. It's been nothing but a PITA to me and from an accidental user's perspective it seems like a hot mess full of bad practices and assumptions. Perl, Ruby, and Node.js toolchains have all been kinder and saner for me.
