It's possible you were only looking for a cheap laugh, but this comment by TimToady addresses the issue you were joking about. Notably:

Maybe it would help if you thought of Perl 6 as something more like Perl 16 or so. We're just trying to skip over the 20 years of deprecation cycles and dead ends it would take to evolve Perl 5 into Perl 16 piecemeal, even assuming that were culturally possible, which it really isn't.
