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.

Hi, Thank you. I have applied your patch and released Mouse 0.63. Mouse's test policy I think is to copy tests from Moose's distribution, fixing them as little as possible. In this case I did so. Regards, -- Goro Fuji (gfx) GFUJI at
