NAME

Moose::Policy::SingleInheritence - Why would you ever need more than one?

SYNOPSIS

   package Foo;
   
   use Moose::Policy 'Moose::Policy::SingleInheritence';
   use Moose;
   
   package Bar;
   
   use Moose::Policy 'Moose::Policy::SingleInheritence';
   use Moose;
   
   package Foo::Bar;
   
   use Moose::Policy 'Moose::Policy::SingleInheritence';
   use Moose;
   
   extends 'Foo', 'Bar';  # BOOM!!!!

DESCRIPTION

This module restricts Moose's "extends" keyword so that you can only assign a single superclass.

This is mostly an example of how you can restrict behavior with meta-policies in addition to extending and/or customising them. However, sometimes enforcing a policy like this can be a good thing.

BUGS

All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to cpan-RT.
