To my knowledge, Rakudo hasn't reached the point where its developers call any Star (runtime plus libraries) release a "major release" of the sort that users ought to use in the wild for a year or more.
Monthly releases are a good step in the right direction, but they aren't very useful to those of us who need something more robust.
Perl 5 currently offers this robustness, while Rakudo unfortunately does not. The other Perl 6 implementations end up being worse than Rakudo in this respect, as well.
But right now, especially once Perl development really picked up, it might be time to "divorce" the two languages. It seems more like Algol60 vs. Algol68, or Modula-2 vs. Modula-3. Sure, there's a number in there, but it isn't just about the version of the main implementation.
Having said that, kudos to the Perl team. I really like that they now release new versions pretty regularly, which is a good sign to show people that Perl5 ist still very much alive and nobody needs to hold their breath for the time being.
If only I could use something more recent than 5.8 at work...
Non-Perl devs won't switch to Perl6 because the P word scares them.
So, yes, changing the name might be a good idea.
And making an enjoyable web-based tutorial.
I will.
But hey, generally it's not a big hassle, from a programmer's perspective that version ain't that outdated. About the only thing I really miss is "//="...
