Announce: Rakudo Star Release 2015.09

Does Perl 6 use $a and $b in sorting?

Because of the the special significance of $a and $b in Perl 5's sort comparison, I always avoid using the names in examples, lest it set a booby-trap for later. I've noticed "a" and "b' being used in some P6 examples. Are they no longer significant, or are they just a poor choice of identifier?

Re: Does Perl 6 use $a and $b in sorting?

sort accepts something callable with an arity of 2. Subroutines, blocks and pointies will do: say sort { $^a cmp $^b }, 5, 3, 2, 6, 4 OUTPUT«(2 3 4 5 6)␤» say sort { $^left cmp $^right }, 5, 3, 2, 6, 4 OUTPUT«(2 3 4 5 6)␤» say sort -> $a, $b { $a cmp $b }, 5, 3, 2, 6, 4 OUTPUT«(2 3 4 5 6)␤»
