Go allows deferring an implementation of an interface to a member of a type. It is somewhat unintuitive, and I think the field has to be an unnamed one.

Similarly, if a field implements a trait in Rust, you can expose it via `AsRef` and `AsMutRef`, just return a reference to it.

These are not ideal tools, and I find the Go solution rather unintuitive, but they solve the problems that I would've solved with inheritance in other languages. I rarely use them.
