As someone who only got experience in Haskell I have to ask the same thing. Why should I use X OOP language when I can write almost anything in Haskell with ease? I tried learn programming in C and Python and even the beginner language Scheme, still I did not get programming until I learnt Haskell. Code shouldn't be abstracted as real world objects becuase code is instruction not something concrete you can touch, its information. Abstracting it using a more mathematical approuch very much makes sense and let even a beginner be able to handle quite complex problems.
