Uhhm, let's reopen this: first it's a 4.6 Regression too, second we are still
not Ok for impl template, eg:

template <class V>
  struct impl
  {
    template <class T> static T create();
  };

template <class T, class U, class V, class
      = decltype(impl<V>::template create<T>()
             -> impl<V>::template create<U>())>
struct tester { };

tester<impl<float>*, int, float> ti;
