Statements control the move of Handle (except for functionality calls and exception throws, which are expressions).
An API course and its members can’t are now living in an unnamed namespace; but any “helper” course or functionality that is certainly defined within an implementation resource file really should be at an unnamed namespace scope.

Thus, to create appropriate code, we often really have to do additional than just follow the formal specification.
