Sommaire

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.
