Which functional language?

I want to learn a functional programming language from the Lisp dialect but I'm not sure which one to pick. I want to be able to do practical things with it so I was thinking about Clojure. Does /prog/ have any suggestions?

if you want to learn Lisp, then go with CL or Scheme. Clojure is sort of a hybrid that experiments with non-lisp syntax (non-paranthesis). I would recommend Scala over Clojure by a long shot if you are already familiar with Java.
