I guess, the way to defend it would be by demonstrating expressiveness. Syntax hardly matters. - Closures (I guess blocks might achieve the same, never worked in Obj-C) - Lambdas - Dynamic Typing or Type Inference. You need at least one of those. - Or any other construct that enhances expressiveness.
