Not sure I understand the question.
I guess you'd like this to work for some library pseudo-tuple type
- I've not looked at those, somebody else may give you a better answer.

"Native" tuples already support what you're asking for:

   template Tuple(A...) { alias Tuple = A; }

   void main(){
     alias T=Tuple!(int,double);
     pragma(msg,T[0].stringof);
     pragma(msg,T[0..2].stringof);
     pragma(msg,typeof(T.init[0]).stringof);
     pragma(msg,typeof(Tuple!(T.init[0..$])).stringof);
   }
