Raymond, I pretty much agree with your points and would be happy either with rejection or one simple sentence. This idiom really belongs in a hypothetical how-to, such as 'Python iterators and generators'. The real use case for it=iter() followed by next(it) it to treat the first item of a collection specially before scanning the rest in a for loop.
