=head1 NAME

Data::Rx::Type::MooseTC - experimental / proof of concept Rx types from Moose types

=head1 VERSION

version 0.007

=head1 SYNOPSIS

  use Data::Rx;
  use Data::Rx::Type::MooseTC;
  use Test::More tests => 2;

  my $rx = Data::Rx->new({
    prefix  => {
      moose => 'tag:rjbs.manxome.org,2008-10-04:rx/moose/',
    },
    type_plugins => [ 'Data::Rx::Type::MooseTC' ]
  });

  my $array_of_int = $rx->make_schema({
    type       => '/moose/tc',
    moose_type => 'ArrayRef[Int]',
  });

  ok($array_of_int->check([1]), "[1] is an ArrayRef[Int]");
  ok(! $array_of_int->check( 1 ), "1 is not an ArrayRef[Int]");

=head1 PERL VERSION

This library should run on perls released even a long time ago.  It should work
on any version of perl released in the last five years.

Although it may work on older versions of perl, no guarantee is made that the
minimum required version will not be increased.  The version may be increased
for any reason, and there is no promise that patches will be accepted to lower
the minimum required perl.

=head1 WARNING

This module is primarly provided as a proof of concept and demonstration of
user-written Rx type plugins.  It isn't meant to be used for serious work.
Moose type constraints may change their interface in the future.
