I asked Omitting the second part of the ternary operator when I was dead tired, and made a mistake that changed the nature of the question.

I still want to know the answer to the "real" question, but the "wrong" question generated quite a bit of discussion. Apparently a number of people found it interesting (they seem to have been unaware of the feature under discussion).

I want to re-ask the "real" question. What to do with the "wrong" one?
