OK, sorry.
The proposal is still getting more complicated, though, and I really
don't see how it's better than having some low-level helper functions
for people who need to build custom __hash__ implementations. The "one
obvious way" to customise hashing is to implement __hash__, not to
derive from a base class that says my class is an
Immutable{Iterable,Set}.
