This doesn't check for idiomatic assignment, unfortunately. For instance, it allows `T &operator=(T)` which is a copy assignment, but not generally considered an idiomatic one. (Similar for allowing `volatile`-qualified parameters.) If we want to go with such a check, I would not be opposed to it, but we should definitely discuss what "idiomatic" means.
