   Perhaps the exact type is not always important to the user, such as in   
   this Proto-example. What is important though is the underlying concept   
   the type implements. However, without support from the language the   
   concept would have to be looked up from the documentation; I could   
   live with that:) But something like this would be even nicer:   
      
         auto[Grammar_Concept] f();
