Very good question, and an awesome explanation. (Apart from one small type that you probably put in deliberately to prove that you're still human).
Thanks, Tom!

Great question Tom, with a couple of wee pitfalls to lead the unwary, fortunately I had remembered my wits today. Superb explanation too.

Yes, I saw the NULL issue immediately, and then hit one of the checkboxes. Didn't even stop chewing my breakfast to contemplate datatype precedence. Nicely posed and explained.
