So, well, now that my code compiles (well, C code, not Perl 6 code :-)) I’ve time to describe Perl 6 changes, instead of simply doing what XKCD says - I shouldn’t waste time.
Rakudo Perl 2012.11 is now released. The change mentioned in this article is already in.
NativeCall module is now part of specification.trait_mod routines are evaluated in sink context.--> (return type) acts more like a normal subroutine parameter.:($a, $b) := \(1, 2) updates $a and $b instead of doing nothing.
