hmmm it looks worse now... if our previous suggestion is hard to implement,
I'll suggest to do a coroutine lookup here. For example, we know a class is
marked with coro_lifetimebound attribute, then we should be able to find the
corresponding promise_type, right? And if yes, we can give exceptions to the
member functions of the promise_type so that we can cover the case here.
