 * @assertion On the other hand, it is possible to return the result of a void
 * method from within a void method. One can also return null; or a value of
 * type Dynamic. Returning any other result will cause a type warning. A compile
 * time error would arise if a non-null object was returned from a void method
 * (since no object has runtime type dynamic).
 * @description Checks that returning a non-null value with non-dynamic static
 * type from within a void method produces compile error.
