And yet it's trivial to write a highly multithreaded application with STM in most CL implementations today.
If Clojure was less inclined to differentiate itself from other Lisps and co-opting the future of the language I believe there'd be far less zealotry on both sides of the fence. IMO Clojure is just fine. I don't see the reason why it needs to persist CL FUD in order to make its case. They're both very practical implementations of Lisp after all.
