I won't promise it'll convince me, but it'll certainly be a
starting-point for real discussion. Also, it's a fairly coherent
"library-style" module - a nice warm-up. So, when you're ready for a
REAL challenge, annotate tkinter :)

Actually, annotating the builtins might be worth doing too. Either
instead of or after pathlib.
