I created a new class specifically because I thought `GenericSetter` wouldn't work with `ArrayRef` because we need a copy. I'm not sure if we can make it work with `ArrayRef` (maybe adding some template specialization that always copies if the getter returns an `ArrayRef`? not sure if that's actually possible).

We can always revisit this if we see more instances of getters that return ArrayRef that we could generalize. For now, this is a one-off so I think it's okay to keep it as is.
