   Ok, that can be done. And what is the benefit of that really? Also, I   
   imagine a situation, where a function was originally:   
      
   void Foo(A a, B b)   
   {   
    ...   
    Global().Bar();   
   }   
      
   After rearranging there no more Global(), but you have reference in both   
   A and B. And here you will keep wondering what on earth to do.   
      
   Call which one, or both? Or start comparing references? Or require an   
   extra param, and pass the problem up one level?
