The comment that you -- with aloof disbelief -- replied to only talked about pointers. I don't know what point you think you are proving with these pithy replies. It sure does go above my head. :)
Well, this is a thread about storing sql null. I'm trying to suss out how sane languages represent sql null in a way that can't go wrong. So far the answers mostly seem to be use a type that can't represent sql null or use a type that explodes when you use it wrong. With a side of real programmers don't let bugs pass code review.
