On: The Next Step for Generics

[richardwhiuk]

The code ends up looking like:

  Optional<Integer> foo;

  //....

  if (foo != null) {
      foo.and_then(new Consumer () {
            function accept(Integer foo) {

            }
      });
  }

I would never assign null to an Optional nor use a library that returned one.

To ensure assignment before use make it final.
