That's because Argument Clinic is generating methoddef with METH_FASTCALL:
$ grep FASTCALL Modules/clinic/_bisectmodule.c.h
{"bisect_right", (PyCFunction)bisect_bisect_right, METH_FASTCALL,
bisect_bisect_right__doc__},
{"insort_right", (PyCFunction)bisect_insort_right, METH_FASTCALL,
bisect_insort_right__doc__},
{"bisect_left", (PyCFunction)bisect_bisect_left, METH_FASTCALL,
bisect_bisect_left__doc__},
{"insort_left", (PyCFunction)bisect_insort_left, METH_FASTCALL,
bisect_insort_left__doc__},
Instead of METH_VARARGS|METH_KEYWORDS:
- {"bisect_right", (PyCFunction)bisect_right,
- METH_VARARGS|METH_KEYWORDS, bisect_right_doc},
- {"insort_right", (PyCFunction)insort_right,
- METH_VARARGS|METH_KEYWORDS, insort_right_doc},
- {"bisect_left", (PyCFunction)bisect_left,
- METH_VARARGS|METH_KEYWORDS, bisect_left_doc},
- {"insort_left", (PyCFunction)insort_left,
- METH_VARARGS|METH_KEYWORDS, insort_left_doc},
