Well, that's not entirely true. They need to be not mutated while they

list.__eq__ to also compare by identity, too. Then you could mutate
the lists to your heart's content and the dictionary wouldn't care.
at which point you'd start wondering if it wouldn't be more efficient to
wrap the list in a light-weight class, instead of using subclassing.
Fair point.
