/**
 * @assertion Evaluation of an await expression a of the form await e proceeds
 * as follows:
 * ...
 * If e raises an exception x, then an instance f of class Future is allocated
 * and later completed with x. Otherwise, if e evaluates to an object o that is
 * not an instance of Future, then let f be the result of calling
 * Future.value() with o as its argument; otherwise let f be the result of
 * evaluating e.
 * Next, execution of the function m immediately enclosing a is suspended
 * until after f completes.
 * @description Check that execution of the function m immediately enclosing a
 * is suspended until after f completes. Test instance methods
