Will this change the result of hashing a long? I know that both gmpy and SAGE use their own hash implementations for performance reasons. I understand that CPython's hash function is an implementation detail, but there are external modules that rely on the existing hash behavior. Yes, it would change the hash of a long. What external modules are there that rely on existing hash behaviour? And exactly what behaviour do they rely on?
Depending on specifics of CPython's hash is a 'do at your own risk' enterprise, like CPython bytecode hacks.
