Personally, I think that Rust's Option and Result are not well suited to Go. Option may serve a purpose, but the language was not built around these constructs.

It's best (still IMO) to use generics to avoid code repetition, not to build semi-mathematical abstractions for their own sake right now. With time, we'll know how to use generics properly.
