Maybe if you drop support for the "separate protocol" alternative... :-)

I had never heard of that PEP. How much code is there in the field?
Written by whom?

I suppose you can always write a decorator that takes care of the
mapping. I suppose it should catch and ignore the StopIteration that
__exit__(StopIteration) is likely to throw.
