Do we really want to add a syntactic feature which has such a complicated expansion? I fear it will make code using "yield from" much more difficult to understand and audit.
As I've said before, I don't think the feature itself is difficult to understand. You're not meant to learn about it by reading the expansion -- that's only there to pin down all the details for language lawyers. For humans, almost all the important information is contained in one paragraph near the top: "When the iterator is another generator, the effect is the same as if the body of the subgenerator were inlined at the point of the ``yield from`` expression. Furthermore, the subgenerator is allowed to execute a ``return`` statement with a value, and that value becomes the value of the ``yield from`` expression." Armed with this perspective, do you still think there will be difficulty in understanding or auditing code? -- Greg _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
