Message 286650 - Python tracker
str type still has a few methods using METH_VARARGS (slower than METH_FASTCALL): * count() * find() * index() * rfind() * rindex() * startswith() * endswith() * format() Maybe I will propose a change later to convert these methods to Argument Clinic, but I consider that the initial issue "Currently, Argument Clinic doesn't use METH_FASTCALL for these methods, but METH_VARARGS" is now fixed, so I close the issue. Thanks Naoki and Serhiy.
