I would note that Rust macros are actually working with structural typing: the expanded macro cannot be compiled unless the expressions/statements it results in can be compiled.
Regarding Scala here, it seems a weird idea to ask that each and every method should copy+paste the interface. We all know the woes of duplication. Instead, you can define a Trait (even if for a single function) and it'll just work; and when you add a second function you will be able to re-use the same trait.
