=head1 NAME

MooseX::Types::UUID - UUID type for Moose classes

=head1 SYNOPSIS

  package Class;
  use Moose;
  use MooseX::Types::UUID qw(UUID);

  has 'uuid' => ( is => 'ro', isa => UUID );

  package main;
  Class->new( uuid => '77C71F92-0EC7-11DD-B986-DF138EE79F6F' );

=head1 DESCRIPTION

This module lets you constrain attributes to only contain UUIDs (in
their usual human-readable form).  No coercion is attempted.

=head1 EXPORT

None by default, you'll usually want to request C<UUID> explicitly.
