In dmd is order of module compilation different.
Same problem:

https://run.dlang.io/is/NkySAw

This is not only problem with imports:

```d
class Foo{
     Bar.B b;

     static if(true)
     	alias F = int;

}

class Bar{
     Foo.F f;     //Error: no property `F` for type `onlineapp.Foo`

     static if(true)
     	alias B = int;

}

void main(){}
```
