BTW, what happens when__iter__() raises StopIteration?

The exception is raised before the generator is created and the traceback shows the iterable as the location of the exception.

Is similar change needed for asynchronous generators?

I don't think asynchronous generators were ever changed, so they still have the old behavior from 3.13 and earlier.
