Where do you get the information about aiming for release in a couple of years?
I gave up trying to find out a while ago.
Probably from raiph. I saw that he mentioned that several times on Reddit. Also see the comments on my blog post: http://blogs.perl.org/users/steven_haryanto/2013/03/dont-wai... (18 months).
Having said that it would be pointless to go simply rewrite existing Perl 5 code to Perl 6. A good deal of Perl 5 libraries will be ported to Perl 6. And then Perl 6 will be well suited for a lot of big projects.
Perl 6 has a very nice type system, packed with all the goodies of a enterprise object oriented language,it has powerful functional programming features, and with all that it stays true to its scripting roots.
The right way to look at it is, Perl 5 and 6 will co exist for much of their individual lifetimes.
