   You can put a typedef there. Declarations are instantiated immediately,   
   so the following will instantiate the static data member properly as   
   soon as PrintingYou is instantiated.   
      
   template   
   struct PrintingYou {   
      static PrintMe pm;   
      
      template struct Value;   
      typedef Value ref_type;   
   };
