Yes. It was just an example. (regarding Use A::n). Sorry for my rush))

To be honest: I would be so glad to share all my code but it is toooo long (15 modules now and a lot of files calling them). I use always some tricks to go over that issues but now I am done to do that and want to find a really charm idea how to beat that issues)).

I am really happy you caught the idea of circularity between packages. This is the very problem.

Sometimes it says: cannot locate method "new" via package "blabla::1" or so... It hurts me so much))
