It seems like a stretch to classify Julia as Object Oriented. It has types and record structures, but these aren't strongly coupled to functions like you'd see in most OO-style approaches. It also doesn't encourage hiding data behind a bunch of "accessor" methods on objects.

There also isn't OO-style inheritance and polymorphism. Julia's multi dispatch reminds me most of Clojure's protocols, which is a great feature. It achieves polymorphic behavior of functions without having to do ugly things to the objects. That Julia can make this fast and ubiquitous in the language is pretty awesome.

I'm also new to Julia, but I really like the above design decisions, among others features.
