I believe in code we will not call && overload.
One reason is I think is that named rvalue reference is lvalue reference
Second is that we are anyway calling std::move on wrapper, not on stored
member, i.e. wrapper result function does not destroy/move/reset member.

auto result() {
    return h.result();
}
