Is the whole notion of a frozendict worthy, given this limitation?
I don't think so. Of course we how have a more general problem: - if we choose to implement only equality testing for partials and leave hashing as is, then hashing isn't consistent with equality anymore -- which is unacceptable - if we choose to implement only equality testing for partials and make them unhashable, we are breaking programs which store partials in a set or a dict
So we are left with the following choice: - implement hashing consistently with equality testing, even though the keyword arguments can be changed later. I think this is acceptable from a practicality standpoint - abandon the whole idea of improving equality testing
