I did that, but it's not enough. See Bug 102524.
I export a `detail` namespace like this to workaround the issue in its parent
namespace:
```C++
export module waarudo.details.workaround_gcc_bug_100617;
export namespace waarudo::detail {
void workaround_gcc_bug_100617() { }
} // namespace waarudo::detail
```
