   OK then.  Please consider the code below, and write a script that will   
   correctly rename file-scope function "A" in File1 to "C", as well as all   
   calls to it from both files.   
      
   // File1:   
      
   int A(int x) { return -x; }   
   int B(int y) { return y*3; }   
      
   template   
   A F(A a, B b) { return A(a*b); }   
      
   // File2:   
      
   int A(int x);   
      
   namespace   
   {   
      
   struct B   
   {   
     B() : A(0) { }   
     int A;   
   };   
      
   struct X   
   {   
     X(int z) : Z(A(z)) {}   
     int Z;   
   };   
      
   }
