Is there a way for singletons that import each other, use each

Like i.e:
------
module sing1;
import sing2;
final class Singleton_1{
static this{
instance = new Singleton_1();
}
static Singleton_1 getInstance(){
return instance;
}
void foo(){
writeln("Sample");
}
void bar2(){
Singleton_2.getInstance().bar();
}
private:
static Singleton_1 instance;
}
-------
module sing2;
import sing1;
final class Singleton_2{

without triggering the "cycle between modules with
constructors/destructors"?
- You can use a 3rd module that imports the two that "cycle".
- You can use another singleton implementation that doesn't rely
on a static this. e.g a kind of "lazy factory" that control the
uniquness.
