NAME
Perl::Critic::Policy::BuiltinFunctions::RequireBlockMap - Write "map { $_ =~ /$pattern/ } @list" instead of "map /$pattern/, @list". AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
The expression forms of "grep" and "map" are awkward and hard to read. Use the block forms instead. @matches = grep /pattern/, @list; #not ok @matches = grep { /pattern/ } @list; #ok @mapped = map transform($_), @list; #not ok @mapped = map { transform($_) } @list; #ok CONFIGURATION
This Policy is not configurable except for the standard options. SEE ALSO
