This is a good solution! I don't directly use `iter` very often so I only remember it's simplicity part of the time. Sadly, this is not the idiom I see in most places. I will say, though, that I was not comfortable using iterators when I first learned python; walrus strikes me as easier to grok for a novice (one of the ostensible Python target demographics) than iter. I'll bet this is why this simple form is not idiomatic (though you're right, it should be).
