   Ok, default arguments may be debatable but I would still like to see a   
   discussion why it would be bad to allow /class.../ to substitute /class/   
   like this.   
      
   template   
   class EllipsisTemplate;   
      
   template class T>   
   class TakeTemplate   
   {   
   };   
      
   int main()   
   {   
      std::cout <<   
         typeid( TakeTemplate ).name() <<   
            std::endl;   
      
      return 0;   
   }   
      
      
   Regards,
