Comment:

 Replying to [comment:15 vorner]:

 > So I don't want to flatten the two classes into one. I just want to get
 the iterator without an explicit call.

 After researching (googling) the guts of Python iteration, I think I
 finally understand. By moving `ZoneTableAccessor_getIterator` from
 `tp_methods` to `tp_iter`, I can make `ZoneTableAccessor` iterable, while
 still preserving `ZoneTableIterator` as the iterator itself (but mostly
 invisible to the app).

 Like I said, I was led astray by the `DataSrcClient` wrapper, which has
 its own problems, but I'm not going to try to fix them in this ticket.
