Perl::Critic::Policy::BuiltinFunctions::ProhibitReverseSortBlock - Conway says that it is much clearer to use reverse than to flip $a and $b around in a sort block. 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.
