Perl::Critic::Policy::BuiltinFunctions::RequireBlockMap(3)
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.
