You've proposed a "what", but I don't see a "why". Indeed, it will break some code. I've been (currently legally) expressing __slots__ as sets, which is arguably more consistent with its purpose, and in testing appeared to perform better than tuples. So, I would request that you amend the allowed types to include sets. Also, people are using dicts to provide docstrings on attributes, so that would need to be addressed as well.

Actually it will break more code, because initializing __slots__ with a list is pretty common. Maybe restrict it to tuple or list? But having an immutable __slots__ may be more reliable.
