Well, that makes a big assumption. The assumption being that there will actually be a Perl5 release before Perl6. It's been almost a year since 5.9.1 was released, with no 5.9.2 appearing at the horizon.

Well, but then even if I'm not involved into anything having even remotely to do with p5p, it's hard to believe that 5.9 won't make into 5.10 which is a "next major release".

So, for various reasons, I think it's unlikely much of the perl6 goodies will get implemented into perl5. Which is a pity.

Hmmm this sort of things are hard to predict, longterm. And Perl6 development is guaranteed to take quite a while. Just the other day Larry wrote in p6l:

Me too.  If it's any comfort, just think of the design of Perl 6 as
a genetic algorithm running on a set of distributed wetware CPUs.
We'll just keep mutating our ideas till they prove themselves adaptive.
