<pre>Clang rejects this valid code:
template<typename T> struct A {
template<typename U> struct B {};
template<typename U> struct B<U*> {};
};
template<> template<typename U> struct A<int>::B { typedef int type; };
A<int>::B<int*>::type x;
Here, per [temp.class.spec.mfunc](14.5.5.3)p2, A<int>::B<int*> uses the
explicit specialization of A<int>::B, not the partial specialization from A<T>,
so this code should be valid. But clang picks the partial specialization from
inside A<T> and rejects it.</pre>
