I am now a bit confused about the semantics of __eq__ for WeakSets. Is a
WeakSet only equal to another WeakSet with the same elements or to any
iterable with the same elements, e.g. list? Because this is how I read
the current implementation. If it is the latter, when should a
NotImplementedError be raised? Whenever the other object is not an Iterable?
