I think you're making a vast assumption that the case is rare.
When I write utility functions, I want them to work on as wide a variety of
inputs as possible. Otherwise, they are not very useful.

That's just what I wish to avoid. Consider adding more pointer types - the
combinatorics quickly explode. Heck, just have two pointer parameters, and you
already have 4 cases.
I wonder how Rust deals with this.

Good question. I don't have an answer offhand.
