Detailed Description

Run a module-level `async def` as a plain function where it is awaited.

With no other task to switch to, `await f(x)` and `asyncio.run(f(x))` run the
body of `f` to completion like `f(x)` would, and a call that is never awaited
evaluates its arguments without running the body. A coroutine used any other
way (stored, passed, scheduled) is refused, as is awaiting anything else.
