If it's really enough to understand and debug all corner cases of using "yield from", then fair enough.
In the case where the subiterator is another generator and isn't shared, it's intended to be a precise and complete specification. That covers the vast majority of the use cases I have in mind. Most of the complexities arise from trying to pin down what happens when the subiterator isn't a generator, or is being shared by other code. I don't know how the specification could be made any simpler for those cases while still being complete. Even so, the intention is that if you understand the semantics in the generator case, the behaviour in the other cases should be something reasonable and unsurprising. I certainly don't expect users to memorize either the expansion or the full text of the English explanation. -- 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
