Okay, I see what you mean now. That's a bug in the expansion. Once an iterator has raised StopIteration, it has presumably already finalized itself, so calling its close() method shouldn't be necessary, and I hadn't intended that it should be called in that case. I'll update the PEP accordingly. -- Greg
