https://www.python.org/dev/peps/pep-3102/ Replaces the pattern: self.name = kwargs.pop('name') Keyword-only arguments offer some advantages: - In the event of a typo or misuse, a more informative error is presented to the programmer. - More self documenting and makes interfaces more explicit. - They more easily allow explicit typing. Adding types to ConfigOptionParser required changing some call sites to pass arguments without using a dict due to mypy bug: https://github.com/python/mypy/issues/9676 |
