What OOP gets wrong about interfaces and polymorphism
I often receive feedback to my general OOP critique from people somewhat sympathetic to my message suggesting that since OOP is vague and not precisely defined, it would be more productive to talk about its core tenets/features in separation and drop the “OOP” name altogether.
I've also received an email (hi Martin!) asking among other things on my opinion about usage of interfaces in OOP. So instead of writing a private response, I'm just going to dwell a bit more on it in a blog post.
BTW. I'm continuing to read #oop #books to gather more insight and arguments. Currently, I am going through Object-Oriented Software Construction by Bertrand Meyer. The book is huge and presents the case for OOP in-depth, which is perfectly fulfilling my needs. And on top of it – it's old, so it gives me a lot of insight on “what were they thinking?!” ;). Hopefully, I'll get to a post about it in the not-too-distant future, but I will be referring to it already in this post.
Anyway... about the polymorphism and stuff...
