* @assertion Let T be the static type of e and let f be the immediately
* enclosing function. It is a static type warning if T may not be assigned
* to the declared return type of f. If f is synchronous it is a static type
* warning if T may not be assigned to Iterable. If f is asynchronous it is
* a static type warning if T may not be assigned to Stream.

* @description Check that compile error is issued, if the body of f is marked
* async* and the type T may not be assigned to the declared return
