Grump. If you think you know a better way to program than some kid way, the thing to do is write an exemplary program and let kids see it. Not to lecture kids about how they're doing it wrong. For kids, there's no such thing as "doing it wrong." Kids aren't professionals. Whatever is fun for them is "right." This was a subtlety of Logo design; the language made it easy to program in ways we approved of, but we didn't lecture kids about those ways. Whatever a kid does is fine.
