NAME

PerlX::Define - cute syntax for defining constants

SYNOPSIS

   use v5.12;
   use strict;
   use warnings;
   
   package MyMaths {
      use PerlX::Define;
      define PI = 3.2;
   }

DESCRIPTION

PerlX::Define is a yet another module for defining constants.

Differences from constant.pm:

  • Cute syntax.

    Like constant.pm, constants get defined at compile time, not run time.

  • Requires Perl 5.12 or above.

    If you're lucky enough to be able to free yourself from the shackles of supporting decade-old versions of Perl, PerlX::Define is your friend.

  • Only supports scalar constants.

    List constants are rarely useful.

    Your constant can of course be a reference to an array or hash, but this module doesn't attempt to make the referred-to structure read only.

  • Doesn't try to handle some of the things constant.pm does like declaring constants using fully-qualified names, or defining constants pointing at magic scalars.

Prior to version 0.100, PerlX::Define was bundled with Moops.
