           Summary: Public alias to private struct template in struct
                    instantiated in UDA is not visible from module
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux

import_a.d:

```
struct S {
    public alias A = T;
}
private struct T() { }
```

test.d:

```
import import_a;

@(S.A!())
void main() {
}
```

Worked as of 2.102.2, but on master says

```
test.d(4): Error: `import_a.A!().T` is not visible from module `test`
```
