Unfortunately I have to chase some pointers, which are pointing to a class
having virtual functions.
I'm stuck for now, probably messed up some casts? Ah, writing pretty
printers is dark magic.

Yes, I planed to make use of the other printers as well as the default one.
It's not working yet though.
