Yes, but if you have such a code:

  struct A {
    union {
      union {
        struct B {};
        using T = B;
      };
    };
  };
  void f(A::T);

you have `?f@@YAXUB@<unnamed-tag>@2A@@@Z` for `f`, and for such a code:

  struct A {
    union {
      union {
        struct B { struct C {}; };
        using T = B::C;
      };
    };
  };
  void f(A::T);

you'd have `?f@@YAXUC at B@<unnamed-tag>@3A@@@Z`. What are `2` and `3` in general? I don't know whether the aforementioned code is acceptable according to the standard, honestly. But if I put a code into the common place, I should figure out the common algorithm.
