=head1 NAME

Moose::Cookbook::Extending::Recipe2 - Providing a role for the base object class

=head1 SYNOPSIS

  package MooseX::Debugging;

  use strict;
  use warnings;

  use Moose::Exporter;
  use Moose::Util::MetaRole;
  use MooseX::Debugging::Role::Object;

  Moose::Exporter->setup_import_methods();

  sub init_meta {
      shift;
      my %options = @_;

      Moose::Util::MetaRole::apply_base_object_roles(
          for_class => $options{for_class},
          role      => ['MooseX::Debugging::Role::Object'],
      );
  }


  package MooseX::Debugging::Role::Object;

  after 'BUILD' => sub {
      my $self = shift;

      warn "Made a new " . ref $self . " object\n";
  }

=head1 DESCRIPTION

In this example, we provide a role for the base object class that adds
some simple debugging output. Every time an object is created, it
spits out a warning saying what type of object it was.

Obviously, a real debugging role would do something more interesting,
but this recipe is all about how we apply that role.

In this case, with the combination of L<Moose::Exporter> and
L<Moose::Util::MetaRole>, we ensure that when a module does "S<use
MooseX::Debugging>", it automatically gets the debugging role applied
to its base object class.
