> Yeah other tests broke for me if you don't have a mock proxy, I'm assuming this is down to how any_instance works; I'd be happy with sending two methods from the other, but that seemed more clunky.

Odd, before seeing your comment, I just tried to change this line to `clone.send :__remove_mock_proxy` and I didn't see any failures.  Also, with how `__mock_proxy` is designed to work (e.g. it's a lazily initialized attribute) it would probably indicate a deeper problem that should be addressed if it causes failures for it not to be called.
