/**
 * @assertion 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. The stream associated with the innermost enclosing
 * asynchronous for loop, if any, is paused. At some time after f is completed,
 * control returns to the current invocation. The stream associated with the
 * innermost enclosing asynchronous for loop , if any, is resumed. If f has
 * completed with an exception x, a raises x. If f completes with a value v,
 * a evaluates to v.
 *
 * @description Check that if e evaluates to an object o that is not an
 * instance of Future, then await expression value equals to o.
