Those operators aren't for pointer arithmetic in any language I know of, including Rust, C, C++, or Go. The operators for pointer arithmetic are plus and minus (technically square brackets too in C)--that's why it's called pointer arithmetic.
Ok sorry, I misused the term "pointer arithmetic" then. I think I was referring to memory indirection and the like. I find "ref" and "->" less cryptic than "&" and "*".
That's the point of my suggestion! One looking at them will think they are pointer arithmetic, which is not pretty for newcomers.
