I'm always looking forward to Perl6, waiting for its stable version, for 10 years.

I think perl 5.10 and beyond kind of preempted perl 6.

Alas, perl 6 in some ways isn't even perl. Perl 6 is cool, but Larry should have made a new name for his next hobby :-)

Perl 5 and Perl 6 are two different languages; Perl 6 is a sibling, rather than successor, to Perl 5.

As I understand, it has been going on for as long as Python 3 -- which is starting to be used in a few places now. (The difference is that Perl 6 is really, really, really ambitious. Let's see if it ever gets production-ready.)
