   It depends on what you mean by "better". I don't think your macro adds   
   enough value to offset the drawbacks of being a macro. It could be   
   written as a template:   
      
   template    
   void n_times( N n, const Fn &fn ) {   
        for (N i = N(); i < n; ++i)   
            fn( i );   
   }   
      
   void demo() {   
        n_times( 3, []( int i ) {   
            use( i );   
        } );   
   }   
      
   I'd say that does a better job of encapsulating the logic - for   
   example, by preventing the loop body from modifying the loop counter -   
   but the usage syntax isn't especially simple.
