[Python-Dev] Re: A proposal to modify `None` so that it hashes to a constant

Whether determinism is fundamentally good or fundamentally bad depends heavily on context.

Agreed 100%. Unfortunately in Python, you cannot choose your hashing function depending on context. Also, once you've decided to violate determinism somewhere, it's gone. There is no way, in the general case, to bring it back. That's why it's important not to violate it willy-nilly in a manner that cannot even be prevented by users who _want_ their programs to exhibit deterministic behavior.
