> Do you have a use case where `x == y`/`hash(x) == hash(y)` does not mean that `x` and `y` should be interchangeable? True and 1 are 100% interchangeable, minus their str() output, and my example is very unlikely to ever appear in actual code.
No I don't have a use case :)

Incidentally, pypy seems to behave the same as reported here. |
