Perl::CritiPerl::CritiUseroContributediPerlcDocumentationitReverseSortBlock(3)

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

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

DESCRIPTION
       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

CONFIGURATION
       This Policy is not configurable except for the standard options.
