Type constraint ClassName does not work

Hi Stevan,

seems like I found a strange bug at the type constraint ClassName.

Using ClassName as TC in an object, it fails - while using it as
exported function, it works.

Moreover, copying the exact type definition of ClassName from
Moose::Util::TypeConstraints into an own package or into an object
itself, all works as expected.

Sorry, I have no idea, how comes.

Please have a look at

P.S.: My environment:
Perl v5.8.8 on Debian 4.0 Etch
Moose 0.44
Class::MOP 0.55
