I think it would be better not to loop, still return the final value from close, and still just throw GeneratorExit to subiterators without trying to reraise. This sounds better to me too, except for the last part -- not reraising GeneratorExit.
If you re-define close to return the value attached to StopIteration, then I think that it makes sense to define it to continue to return this value on subsequent calls to close. This provides a way to still retrieve the returned value after the generator has been finalized in some other way. And then, wouldn't this allow you to discard the StopIteration in yield from and reraise GeneratorExit to finalize the outer generator; but leaving it the option to call close itself on the inner generator to retrieve the return value, if it still wants it? -bruce frederiksen
