I can get as far as `plot() / 3` but then no idea how to proceed. I don't think overloading arithmetic is a very good way to express this.
Separately you might find this to be smelly design, but then you should remember that this at least has precedence ¯\_(ツ)_/¯
Matrix multiplication? Yeah, everybody knows there's a function being called. And, if it was implemented right, the users almost never have to look at the implementation.
Many other possible uses? Nope. Just nope. Not worth it.
