NAME

       Perl::Critic::Policy::BuiltinFunctions::RequireSimpleSortBlock - Sort blocks should have a single
       statement.

AFFILIATION

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

DESCRIPTION

       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.

CONFIGURATION

       This Policy is not configurable except for the standard options.
