One more question: What is the rationale for + res = (*it->ob_type->tp_iternext)(it); + if (res == NULL) { .. + PyErr_SetNone(PyExc_StopIteration); + return NULL; ? I would think tp_iternext failing to set an exception should not be translated into stop iteration. Instead, builtin_next() should return NULL without an exception set and thus trigger a SystemError.
