Look possible. At first glance, staticSort on the template 
variadic argument based on a predicate template that looks at 
alignment of element maybe.

   struct Tuple(A...)
   {
       staticsort!(pred, A) members;
   }

although with the possibility to name each member this will be in 
practice more complicated
