> The values in tuples cannot change. The values that keys point to in a frozen dict can?
The entries of a tuple cannot be assigned to, but the values can be mutated. The same is true for a `frozendict` (according to the PEP they don't support `__setitem__`, but "values can be mutable").
Tuple entries must be hashable, which (as far as standard library is concerned) means immutable.
Ah. Of course… that’s how the workaround to use tuples as frozen dicts can work in the first place. Slow morning for me!
