+ "the coroutine traits class template is being instantiated using the return "
I am wondering what is the use case here.
Is it to guard against badly designed standard library?
I played around a little and tried to see how I could get to trigger this error with a user-code, but, failed. If I did not specify enough parameters it will default to primary template defined in the <experimental/coroutine>
