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.
