I just noticed a module on PyPI to implement this behaviour on Python
functions:

Tangential to the main topic, but this module doesn’t enforce
positional-only
arguments. It allows you enforce keyword-only arguments like on Python
3:
>>> from positional import positional
>>> @positional(1)
... def replace(old, new):
... ...
...
>>> replace(old='a', new='b')
>>> replace('a', 'b')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File “…/site-packages/positional/__init__.py", line 97, in inner
raise TypeError(message)
TypeError: replace takes at most 1 positional argument (2 given)
