   There exists a library-provided template call_once, that takes a   
   callable object and an optional list of arguments to invoke that callable:   
      
   template   
   void call_once(once_flag& flag, Callable&& func, Args&&... args);   
      
   It guarantees that independent on how often you call call_once, it will   
   ensure that it calls the callable object once per provided once_flag.
