Yeah, I wish they did more Clojure as well. As far as I could tell, it was kind of snuck in about ~12 years ago, and it kind of grew from there.
To be fair, I know people hate on it, but I honestly do kind of think Objective C is kind of a cool language. I think it's ugly but I think the message-passing style semantics are kind of neat.
Adding Smalltalk message passing as an extension to C was very clever and allowed writing very efficient code and dynamic high level UI code in a single language. The semantics were kept clear by the distinctive syntax of message passing. And allowed access to any existing C libraries.
Objective C is neat inasmuch as it managed to add a simple but practical object system to C without all the added baggage of C++. It wasn't without its downsides - in particular, the overhead of a method call was significantly higher than in C++ - but I still appreciate it for its minimalism.
