Perl::Critic::Policy::BuiltinFunctions::ProhibitReverseSUserlContributed Perl DPerl::Critic::Policy::BuiltinFunctions::ProhibitReverseSortBlock(3)NAMEPerl::Critic::Policy::BuiltinFunctions::ProhibitReverseSortBlock - Forbid $b before $a in sort blocks.AFFILIATIONThis Policy is part of the core Perl::Critic distribution.DESCRIPTIONConway 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; #okCONFIGURATIONThis Policy is not configurable except for the standard options.AUTHORChris Dolan <cdolan@cpan.org>COPYRIGHTCopyright (c) 2006-2011 Chris Dolan.
