 Add a failing test for the following construct, which explodes due to metaclass incompatibility:

 package Parent;
 use Moose -traits => ...;
 package Child;
 use base 'Parent';

Skip these tests for now (hopefully this will get fixed in a near-future release)

Do not unimport functions which we explicitly re-export by reference
as-is. This means that Moose _always_ gives you Carp::confess,
Scalar::Util::blessed, etc.
