It’s excellent to return a smart pointer, but unlike with raw pointers the return form cannot be covariant (as an example, D::clone can’t return a unique_ptr.
(Uncomplicated) An assignment operator must return T& to enable chaining, not options like const T& which interfere with composability and putting objects in containers.
