| Subject: | Implement Mouse::Util::TypeConstraints::register_type_constraint() |
Hello.
The attached patch implements
Mouse::Util::TypeConstraints::register_type_constraint() since I need
it, it's simple enough, and it's actually exported by Moose::Util::TC.
I tried to use Moose's own error messages. I didn't know what was your
policy about tests, so I didn't add any.
Regards,
Vincent Pit.
