hmm.. is that really the best way? if the function has 10 lines of code 
and is mixed into to 15 classes thatll give me 15 times the code for that 
one function i think. also gets a bit tricky when i want to override some 
of the functions. (by using another class in between base and derived?). 
i think i need a new plan..
