 ##### Notes
 
-The return value optimization doesn't handle the assignment case, but the move assignment does.
-
 A reference can be assumed to refer to a valid object (language rule).
 There is no (legitimate) "null reference."
 If you need the notion of an optional value, use a pointer, `std::optional`, or a special value used to denote "no value."

 * If a type is expensive to move (e.g., `array<BigPOD>`), consider allocating it on the free store and return a handle (e.g., `unique_ptr`), or passing it in a reference to non-`const` target object to fill (to be used as an out-parameter).
 * To reuse an object that carries capacity (e.g., `std::string`, `std::vector`) across multiple calls to the function in an inner loop: [treat it as an in/out parameter and pass by reference](#Rf-out-multi).
