=head1 PURPOSE
Checks that type constraints continue to work when a L<Moo> class is
inflated to a L<Moose> class. Checks that Moo::HandleMoose correctly
calls back to Type::Tiny to build Moose type constraints.
=head1 DEPENDENCIES
Uses the bundled BiggerLib.pm type library.
Test is skipped if Moo 1.000000 is not available. Test is redundant if
Moose 2.0000 is not available.
