/**
 * @assertion Let f be the function immediately enclosing a return statement of
 * the form return; It is a static warning f is neither a generator nor a
 * generative constructor and either:
 *  • f is synchronous and the return type of f may not be assigned to void or,
 *  • f is asynchronous and the return type of f may not be assigned to
 *    Future<Null>.
 *
 * @description Checks that there's no static warning when a statement of the
 * form "return;" is used in a method that returns type dynamic, or a
 * constructor.
