Oh, you are right. I thought so much about dropping default hash=id,
or more generally that only frozen objects should be hashable, that I
forgot that it's not the case yet... :)

(I used the term "frozen" instead of "immutable" since I think that
"immutable" is not defined very well, because tuples are considered
immutable even though their value can change if they reference mutable
objects.)

Thanks,
