Manual Reference Pages - PERL::CRITIC::POLICY::BUILTINFUNCTIONS::REQUIRESIMPLESORTBLOCK (3)
Perl::Critic::Policy::BuiltinFunctions::RequireSimpleSortBlock - Sort blocks should have a single statement.
This Policy is part of the core Perl::Critic
Conway advises that sort functions should be simple. Any complicated
operations on list elements should be computed and cached (perhaps via
a Schwartzian Transform) before the sort, rather than computed inside
the sort block, because the sort block is called N log N times
instead of just N times.
This policy prohibits the most blatant case of complicated sort
blocks: multiple statements. Future policies may wish to examine the
sort block in more detail looking for subroutine calls or large
numbers of operations.
This Policy is not configurable except for the standard options.
