--- Comment #2 from Nathaniel Shead ---
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;
}
