Thanks for the report. Your example could be boiled down to the following: coro = asynciter() await coro await coro The second call incorrectly returns None but should raise an exception, double awaiting is a programming error. For regular async functions it raises "RuntimeError: cannot reuse already awaited coroutine"

Thanks for the report.

Your example could be boiled down to the following:

coro = asynciter()
await coro
await coro

The second call incorrectly returns None but should raise an exception, double awaiting is a programming error.
