    Due to minor error, the error message for too many positional arguments is not accurate if the function uses Argument Clinic.

    For example:

    >>> int.from_bytes(b'a', 'little', False)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: from_bytes() takes at most 2 positional arguments (3 given)

    This is correct, but not accurate, because from_bytes() takes *exactly* 2 positional arguments.
