Oh, for polysemous values :-) I'm somewhat inclined to say that the result type should be the same as the original type, and if the user wants other behavior they can cast. That keep the simple cases simple, and makes the fancy cases explicit. I'd really rather not have the language trying to second guess me by converting my int to a long just because I used an operation that might overflow.
