Is Erlang Object-Oriented? https://www.infoq.com/interviews/johnson-armstrong-oop https://www.infoq.com/interviews/johnson-armstrong-oop Then, my thesis supervisor said "But you're wrong, Erlang is extremely object oriented". He said object oriented languages aren't object oriented.

Though I must said I am pretty happy with CLOS (Common Lisp Object System), in particular its generic functions.
