3/* A test for equality around interface types
4
5This 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. 
6
7An issue here (perhaps) is that this will compile - the isEqual implementation will just slice and probably not do what the implementer expected.
