Perl::CriPerl::Critic::Policy::ValuesAndExpressions::ProhibitConstantPragma(3)
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.
