I venture to say that the journey to Perl 6 will be harder than the one Perl 5 has taken to its present stage.
in reply to How much Perl6 have we got?
Perl 5 evolved, taking many small steps along the way. It's a bit like a baby growing. You hardly notice it grow but it's growing all the time. Then one fine day it becomes an adult, with all its learned systems of human behaviour.
Perl 6 is like trying to clone an adult. When it's out, it's expected to do what Perl 5 can do, and much more. So it's harder, because it doesn't have the benefit of those evolutionary steps.
