   This seems odd and looks like a compiler error to me. Interestingly the   
   following variant of your code is accepted by MSVC:   
      
   struct Test2 {   
    template  T f() const;   
    int f() { return 4; }   
   };   
      
   template<> int Test2::f() const { return 3; }

   A possible workaround is to use a helper template as follows:   
      
   class Test {   
     template   
     T conv_func_impl() const;   
   public:   
     template    
     operator T() const {   
         return conv_func_impl();   
     }   
     operator int() {   
         return 4;   
     }   
   };   
      
   template<> int Test::conv_func_impl() const { return 3; }
