Mondo changes to the iterator stuff, without changing how Python code sees it (test_iter.py is unchanged). - Added a tp_iternext slot, which calls the iterator's next() method; this is much faster for built-in iterators over built-in types such as lists and dicts, speeding up pybench's ForLoop with about 25% compared to Python 2.1. (Now there's a good argument for iterators. ;-) - Renamed the built-in sequence iterator SeqIter, affecting the C API functions for it. (This frees up the PyIter prefix for generic iterator operations.) - Added PyIter_Check(obj), which checks that obj's type has a tp_iternext slot and that the proper feature flag is set. - Added PyIter_Next(obj) which calls the tp_iternext slot. It has a somewhat complex return condition due to the need for speed: when it returns NULL, it may not have set an exception condition, meaning the iterator is exhausted; when the exception StopIteration is set (or a derived exception class), it means the same thing; any other exception means some other error occurred. 2001-04-23 14:08:49 +00:00			`#define PySeqIter_Check(op) ((op)->ob_type == &PySeqIter_Type)`
