Hmm, if you think about it, it could actually be allowed (interfaces only, classes have an overload problem) - if A is a B and B is an A, obviously A equals B, and they could be merged, while both A and B become aliases to the merged interface.

OTOH, I see no absolutely no use this could have, and it's far more likely that a bug in the code is involved..
