[Edit from Duncan Booth] I would definitely be in favor of a warning. Yes, people should read the docs more carefully, and yes, it would cost a certain amount of annoyance to implement this. But I don't think it would get in people's way if they do know how to use else, and I think it would cut down on the number of questions from mystified beginners, some of whom are much more aggressive than this particular OP about claiming that Python is broken (when it's actually behaving as designed).
