Perl::Critic::Policy::BuiltinFunctions::RequireBlockGrep
The expression form of grep and map is awkward and hard to read. Use the block forms instead.
grep
map
@matches = grep /pattern/, @list; #not ok @matches = grep { /pattern/ } @list; #ok @mapped = map transform($_), @list; #not ok @mapped = map { transform($_) } @list; #ok
