It should be possible to start with a tuple subclass and
add descriptors to provide named access. If the descriptor
is implemented in C it should be just as efficient as
using __slots__, but with no duplication of the references.

Given a suitable descriptor type, it shouldn't be hard to
write a factory function to assemble such classes.
