showing that with a unit test would be good.  also, i think it would
be a good idea to keep Data's public API as closely mirroring nmigen
Value as possible: a constructor instead of create_data, iteration
(__iter__) instead of members(), an eq function, etc.

otherwise it breaks the principle of "least astonishment"
