I have a bunch of classes in c++ with operator== defined, and I exported it as __eq__. They apparently inherited object's __hash__ . All was well until my users started to put these objects in sets and use them as dict keys. Objects that have the compare equal do not have the same hash. This causes weirdness and errors.
I would like to have the __hash__ not exist. These objects are mutable and should NOT be used as keys. Is there a way to hide it? If I have them throw NotImplemented will python do something sensible with that? I suppose the other thing I could do is come up with some bull---- hash function, but I would rather not. The objects really do not belong in sets or dict keys.
