For now I set them to track_never. I'm not 100% sure but for now it 
serves for me and when I need to save through a pointer the trap will
show me that I have to refactor my broken code.

Well, when I'm using a const object I have to cast the constness away 
before I can make a call to any non-const member-function and when I 
have to cast the constness away before searializing how comes it that 
the library knows at all, that this object is in reality a const object?
