I was not carefull whilst simplifying the diagramm.

possibly now I can understand:

          otherClass--->(OtherClass)
                 |         |
                 |         |
                 v         v
              Object--->(Object)
                 ^        |^
                 |        ||
                 |       / |
                 |      /  |
                 |     /   |
                 |    /    |
              Module--->(Module)
                 ^  /      ^
                 | /       |
                 ||        |
                 |v        |
               Class---->(Class)

I'm sorry.

I cannot extract any essence.
