Would that not be "-await coro()"? What "await -coro()" would mean is
to call coro() (which would return something you can wait on), then
apply - to that (then waiting on the result of that negation). But
what does negating an awaitable object mean? Obviously you can
*define* it to mean something, but you probably didn't.
