Nick, you nailed it with your example. In short: current PEP 550 defines Execution Context in such a way, that generators and iterators will interact differently with it. That means that it won't be possible to refactor an iterator class to a generator and that's not acceptable.
I'll be rewriting the whole specification section of the PEP today. Yury _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
