Make function args positional or keyword-only.

In Python, it's possible to force a function argument to be positional-only or keyword-only. In this video, we see the syntax for doing this, as well as see some examples and reasons for why you might want to actually make a parameter positional-only or keyword-only.

Note: positional-only arguments are a Python 3.8+ feature. Keyword-only are Python 3.0+.

Errata:
1. At 1:22 you'll get a TypeError, not a SyntaxError.
