--- Comment #4 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
This is now rejected:

$ xg++ -c 83003.C
83003.C: In substitution of ‘template<class T> using Zod_t = typename Zod::type
[with T = int]’:
83003.C:15:10:   required from here
83003.C:10:26: error: no type named ‘type’ in ‘struct Zod<int>’
   10 | template <class T> using Zod_t = typename Zod<T>::type;
      |                          ^~~~~

So fixed in r270433.
