Orange site is funny, on the topic of the Ideal #Lisp:
"> It would be something like a fusion of Clojure and Common Lisp, (...)
Mine would be, too. Unfortunately, that's not possible. Clojure is one of those few languages actually designed by somebody who knows what they are doing."
So .. the Lisp Machine folks, the Common Lisp people, Maclisp .. etc had no clue what they where doing.
Oh yeah .. Clojure isn't a Lisp, now bite me.
