The code generated by Argument Clinic is correct.
>>> {}.pop(1)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
KeyError: 1
>>> {}.pop(1, None)
It is just a signature wrong. Some earlier versions of Argument Clinic allowed
you to write "default=undefined" to specify an optional argument without
default value, but this feature was lost a long time ago. So now signatures of
some functions with optional arguments are false.
