Rewrite dnd-character to use modules as functions

[ErikSchierboom]

I just came across this: https://www.uiua.org/tutorial/modules#modules-as-functions @vaeng do you think it would make sense to rewrite dnd-character to use this?

I like to show the idea behind the current implementation, but that could work better in a future concept exercise. Feel free to update the exercise, or I can do it after advent of code has concluded

We don't have to rewrite it. We could also do it for another exercise
