if two objects compare equal, then they must have the same hash [...] [you] have to implement a corresponding -hash that maintains this invariant rule.
Is there an example somewhere of what one should do to implement -hash to reflect -isEqual:, I haven't done so in one of my classes and it works fine. Would you just combine the -hash of the objects used to determine -isEqual: in a logical manner, say XOR?
