Perl::Critic::Policy::ValuesAndExpressions::ProhibitConstantPragma(3) User Contributed Perl Documentation Perl::Critic::Policy::ValuesAndExpressions::ProhibitConstantPragma(3)

Perl::Critic::Policy::ValuesAndExpressions::ProhibitConstantPragma - Don't "use constant FOO => 15".

This Policy is part of the core Perl::Critic distribution.

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

This Policy is not configurable except for the standard options.
