New submission from Serhiy Storchaka:
Argument Clinic no longer works single optional argument. For example see
_tkinter.tkapp.wantobjects in the patch in issue20168.
/*[clinic input]
_tkinter.tkapp.wantobjects
[
value: int
]
/
[clinic start generated code]*/
It is converted to the methoddef of type METH_O.
#define _TKINTER_TKAPP_WANTOBJECTS_METHODDEF \
{"wantobjects", (PyCFunction)_tkinter_tkapp_wantobjects, METH_O,
_tkinter_tkapp_wantobjects__doc__},
static PyObject *
_tkinter_tkapp_wantobjects(PyObject *self, PyObject *arg)
{
PyObject *return_value = NULL;
int group_right_1 = 0;
int value = 0;
if (!PyArg_Parse(arg, "i:wantobjects", &value))
goto exit;
return_value = _tkinter_tkapp_wantobjects_impl(self, group_right_1, value);
exit:
return return_value;
}
As result wantobjects() can't be called without an argument.
