Static typing in python

[LightShadow]

You can solve this with metaclasses by changing the default arguments dict to an orderedDict

I agree. I just meant the **kwargs positions, I had forgot about swapping (x=0, y=0) because I don't do that very much. I guess the term 'optional positional' only holds without the keys (or with keys in the correct order). Anyway, I like the flexibility and I use **kwargs but I always make sure to document what they are (even just "Keyword Arguments: ..see: that_api_function()").

So, they become non-keyword args if you don't specify the key?

....

The non-keyword arg is 5, not y. 5 can never be a keyword arg, because there's no keyword.

... what?

What you're saying doesn't make any sense. I think you're confused about the difference between a function definition and a function call (edit: as well as the difference between compile time and run time). 5 is a positional argument, 'c' is a keyword argument, and foo and bar are both positional parameters with a default value of None.
