I think that going with Perl 7 would be good for the Perl community as a whole.

The Perl 6 crew has had over a decade to get something useful put together. While Rakudo is mildly interesting, it isn't practical in the same sense that Perl 5 is. Given Perl 6's lack of traction, I think it's reasonable to consider it a dead effort at this point.

Perl 7, on the other hand, would be very usable right away. It would immediately reflect the changes that we've seen with modern Perl, but without the stigma associated with Perl 6.

At the very least, it would show that the Perl community is again moving in the right directly, with the emphasis on a language that is usable today, rather than on one that has floundered for many years now.
