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.
