--- Comment #2 from Nathaniel Shead <nshead at gcc dot gnu.org> ---
Fixed for GCC 15 so far.  Non-functions don't always work, which is largely
tracked in PR c++/114683. We also might not correctly differentiate unscoped
enums from using enum declarations for this purpose, but it's hard to tell
before PR114683 is fixed.

For instance:


  // using_enum_a.cpp
  module;
  namespace foo {
    enum class a { x, y, z };
  }
  export module M:a;
  namespace bar {
    export using enum foo::a;
  }

  // using_enum_b.cpp
  export module M;
  export import :a;

  // using_enum_c.cpp
  import M;
  int main() {
    auto x = bar::x;
  }
