I'm pretty certain that ActionScript is not an example to the contrary, and I'm fairly fond of it as a programming language.
I'd go so far as to suggest that the majority of the non-Apple tools that people are proposing to use instead of Objective-C will produce an inferior result, and that's why Apple is clamping down on them.
(BTW, love the kneejerk downvoting in this subthread, keep em coming.)
