Very true. Implementation Inheritance should be taught as one of the more obscure features of OOP instead of as one of the main features as it is taught often.

Very true. Implementation Inheritance should be taught as one of the more obscure features of OOP instead of as one of the main features as it is taught often. But in the end we should be less dogmatic in general . Myself and a lot of people I know started out building big inheritance trees only to find out that this didn’t work so well so we reduced it to a degree that was useful and manageable. But then you have some very loud dogmatists who scream “this is not OOP” and insist on building factories and factories of factories and all the other nonsense. And for some reason the dogmatists often get heard, maybe because they are so loud and convinced of themselves.
