/* A test for equality around interface types
This is an attempt to get the *outside* impl of equality to work. The simple case does, but just to throw
a spanner in the works, lets mix in some inheritance.
An issue here (perhaps) is that this will compile - the isEqual implementation will just slice and probably not do what the implementer expected.
