NAME
       Moose::Cookbook::Basics::Recipe11 - Extending a non-Moose base class

VERSION
       version 2.0205

SYNOPSIS
         package My::DateTime;

         use Moose;
         use MooseX::NonMoose;
         extends qw( DateTime );

         has 'mayan_date' => (
             is        => 'ro',
             isa       => 'DateTime::Calendar::Mayan',
             init_arg  => undef,
             lazy      => 1,
             builder   => '_build_mayan_date',
             clearer   => '_clear_mayan_date',
             predicate => 'has_mayan_date',
         );

         after 'set' => sub {
             $_[0]->_clear_mayan_date;
         };

         sub _build_mayan_date {
             DateTime::Calendar::Mayan->from_object( object => $_[0] );
         }

DESCRIPTION
       This recipe demonstrates how to use Moose to subclass a parent which is not Moose based. This recipe
       only works if the parent class uses a blessed hash reference for object instances. If your parent is
       doing something funkier, you should check out MooseX::NonMoose::InsideOut and MooseX::InsideOut.

       The meat of this recipe is contained in MooseX::NonMoose, which does all the grunt work for you.
