Perl::Critic::Policy::ValuesAndExpressions::ProhibitConstantPragma(3pm) User Contributed Perl Documentation NAME Perl::Critic::Policy::ValuesAndExpressions::ProhibitConstantPragma - Don't "use constant FOO => 15". AFFILIATION This Policy is part of the core Perl::Critic distribution. DESCRIPTION Named constants are a good thing. But don't use the "constant" pragma because barewords don't interpolate. Instead use the Readonly module. use constant FOOBAR => 42; #not ok use Readonly; Readonly my $FOOBAR => 42; #ok Readonly::Scalar my $FOOBAR => 42; #ok CONFIGURATION This Policy is not configurable except for the standard options.
