> Python where keyword arguments need to be declared as such.

In Python you don't need to explicitly declare keyword arguments either (though it is possible). This is perfectly valid and working:

    def foo(a: str, b: int, c: bool=None, d: float=None):
        pass

    foo(b=5, a='something', d=3.0)
    # is equivalent to
    foo('something', 5, None, 3.0)
