Whoops! I seem to have left out the template qualifier.

template <typename t>
struct foo {
  template <int n>
  using next =3D typename foo<t>::next<n + 1>;
  template <>
  using next<10> =3D int; // not sure if alias templates can be specialized
};

int main() {
  foo<int>::next<1> x;
}

Although now I am getting a compiler seg fault:

main.cpp:5:13: error: explicit specialization in non-namespace scope =E2=80=
=98struct
foo<t>=E2=80=99
g++-4.7: internal compiler error: Segmentation fault (program cc1plus)
