With larger structs it’s a double-edged sword. Unboxing them also means that the deque implementation has to copy a lot more memory when extending the underlying slices. Unboxing is typically an optimization, for sure. I guess I disagree that it’s a ‘huge’ one except maybe in the case of arrays/slices (where you can do it anyway in Go without generics).
