Regarding null safe oprators

[Lawrence Kesteloot]

I think that your code below should throw an NPE. An empty list is not
the same as a null list. But you could argue that a new syntax would
allow it, like "for (Integer i ?: integerList)". (I would vote against
this too, but only for simplicity, not because it's the wrong
behavior.)
