                                           User Contributed Perl Documentation


NAME
       Perl::Critic::Policy::BuiltinFunctions::RequireBlockGrep - Write "grep
       { /$pattern/ } @list" instead of "grep /$pattern/, @list".

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

DESCRIPTION
       The expression forms of "grep" and "map" are awkward and hard to read.
       Use the block forms instead.

           @matches = grep  /pattern/,    @list;        #not ok
           @matches = grep { /pattern/ }  @list;        #ok

           @mapped = map  transform($_),    @list;      #not ok
           @mapped = map { transform($_) }  @list;      #ok

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