A little bit of self-promotion here...
You don't even need to know Perl 5...
(but it certainly helps)
One of the oldest, but still probably the best
source of examples of Perl 6 features
Not many code examples from 2010 and earlier,
because the compilers weren't as advanced then.
If you speak Perl 5, this will
feel the closest to home.
Lots and lots of examples...
... But not as much explanations.
You don't want to read all of these...
... But if you want to know the juicy details,
this is where you should be headed.
