Clojure is only a Java extension if Java on my machine is an x86 extension. Besides, what's being argued here is that some things should be in the core, not the negativity of an extensible core. I'm somewhat on the fence on the issue. One one hand, it is great to be able to improve your own language. On the other, you are creating/using a forked version of the language, and all the other libraries won't be using your OO -or generic dispatch, or exception or namespace- system, making everything inconsistent.
