   * unnecessary to create a <i>new</i> anonymous inner class implementing {@code Comparator} just
   * to pass it in here. Instead, simply subclass {@code Ordering} and implement its {@code compare}
   * method directly.
   *
   * <p>The returned object is serializable if {@code comparator} is serializable.
