That's a good question, because python offers no simple check a la
`ismutable(x)`. It would be easy to just do a check like `isinstance(x,
(bool, int, float, tuple, str, frozenset))`, if you can live with the
"danger" of users sub-classing those types and making them mutable. But I
guess those can't be helped with this check.
