[Python-Dev] getting rid of default object.hash (SF 660098) (original) (raw)

Would this mean that instances of the following class:

class Dummy(object): pass would no longer be usable as dictionary keys? I guess the parts I'm not clear on are 1) whether dictionaries call the equivalent of 'hash(key)' or 'key.hash()', and 2) whether 'hash(Dummy())' will do something meaningful.

That class would still be usable. hash(Dummy()) sees that there's no eq or cmp override and then uses the default hash.
