I think we might get these eventually in Golang, at least to a degree. In the end it's just a question whether they will be zero-cost like in Rust or incur some runtime overhead (I would assume the latter). Would be fine for me, I rely a lot on reflection for more complex use cases around dynamic typing and that already has a significant runtime cost (which is still ok in most cases).
