…ythonGH-111111) asyncio.TaskGroup and asyncio.Timeout classes now raise proper RuntimeError if they are improperly used. * When they are used without entering the context manager. * When they are used after finishing. * When the context manager is entered more than once (simultaneously or sequentially). * If there is no current task when entering the context manager. They now remain in a consistent state after an exception is thrown, so subsequent operations can be performed correctly (if they are allowed).
