       Perl::Critic::Policy::BuiltinFunctions::ProhibitReverseSortBlock -
       Forbid $b before $a in sort blocks.

       This Policy is part of the core Perl::Critic distribution.

       Conway says that it is much clearer to use "reverse" than to flip $a
       and $b around in a "sort" block.  He also suggests that, in newer
       perls, "reverse" is specifically looked for and optimized, and in the
       case of a simple reversed string "sort", using "reverse" with a "sort"
       with no block is faster even in old perls.

           my @foo = sort { $b cmp $a } @bar;         #not ok
           my @foo = reverse sort @bar;               #ok

           my @foo = sort { $b <=> $a } @bar;         #not ok
           my @foo = reverse sort { $a <=> $b } @bar; #ok
