16 | This tests demonstrates that Moose will not override |
17 | a pre-existing type constraint of the same name when |
18 | making constraints for a Moose-class. |
19 | |
20 | It also tests that an attribute which uses a 'Foo' for |
21 | it's isa option will get the subtype Foo, and not a |
22 | type representing the Foo moose class. |
