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