I am trying to convert an existing module to use Moops instead of Devel::Declare, and as a side effect I find myself converting one of its sub-modules from MooseX::Types::Combine to Type::Library.

Perhaps this task is foolishness, as the project doesn't require this. In any case, I've hit this stumbling block: 

package MyApp::Types;
use strict;
use warnings;

use namespace::autoclean;
use Type::Library -base;
use Type::Utils 'extends';

BEGIN {
  extends 'Types::Standard';
  extends 'MooseX::Types::DBIx::Class';
#  extends 'MyApp::Types::Internal'; # Not needed for this
}

1;
__END__

This gives me the error "coercion => 1 requires type to have a direct parent with a coercion" on the line including MooseX::Types::DBIx::Class.

Does Type::Tiny's strictness about the coercion semantics preclude it from consuming MooseX::Types::DBIx::Class? If so, is there a replacement or work-around?
