In fact with Go is even more obvious. Go don't have inheritance!

Traits is a way to solve it. But the problem is that in Go types are "too open". If you wanna constrain it more traits is not an elegant solution.

Generics is better in this case.

BTW: This is how is in Rust. Rust have traits but you fill the rest with generics.

I made a mini-go database command liner that I call from rust (so I get access to drivers that are not yet available in rust). Is much more boilerplate from some stuff that in the rust side is just Value<T>.

And type errors that Go have that rust don't.

I think that Rust & Go sharing some(most?) design principles (about how model types) make easier to see what each side make harder...
