//oo.Factory// inheriting from //oo.Registry// is a good example for bad inheritance as it is a violaton of the [[https://en.wikipedia.org/wiki/Liskov_substitution_principle|Liskov substitution principle]]. Instead this would be a good case to use [[https://en.wikipedia.org/wiki/Object_composition|object composition]]. OOjs might be a nice approach to get some common way of doing inheritance in different MW extensions and core. OOjs doing the "OO" (**O**bject **O**riented) part wrong internally though does not really shine a bright light on it.
