It is definitely too soon to start betting on perl 6 since we don't have the actual perl6 compiler yet. Sure there's pugs and if you can live with the reference implementation running on top of ghc and can live with random changes as the language (and implementation) evolve, then maybe you would want to bet on perl6.

Personally, I'm going to wait until there's a real compiler (I figure 2-5 years before we have a compiler that's stable enough for production use)
