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.
