Right, there shouldn't be any inheritance. Some of the `public:` access specifications are now redundant, though. Instead of

  template <size_t I, class... Types>
  struct tuple_element<I, tuple<Types...> >
  {
  public:
      typedef Ti type;
  };

we could now simply say

  template <size_t I, class... Types>
  struct tuple_element<I, tuple<Types...> >
  {
      typedef Ti type;
  };
