   * {@code Optional} class. However, this common usage:
   *
   * {@snippet :
   * for (Foo foo : possibleFoo.asSet()) {
   *   doSomethingWith(foo);
   * }
   * }
   *
   * ... can be replaced with:
   *
   * {@snippet :
   * possibleFoo.ifPresent(foo -> doSomethingWith(foo));
   * }
   *
   * <p><b>Java 9 users:</b> some use cases can be written with calls to {@code optional.stream()}.
