Oh, you are right. I got confused by looking at the implementation of PyIter_Check(), which only verifies that tp_next is not NULL. Anyway, _batch_appends() and _batch_setitems() in pickle.py calls iter() on the iterators; so, the iterators must provide __iter__ too. Personally, I wouldn't bother about checking for __iter__ to avoid adding a new method to Pickler and also to save a few hasattr() calls. But I have to admit, it is really just nitpicking at this point. _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue4176> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
