Oh, absolutely. But I wasn't counting Clojure as FP in my comment. There is no definition for FP, and the OP seemed to be talking about the statically typed, pure FP, of Haskell and scalaz. Clojure is certainly not that kind of FP, as it's neither statically typed nor pure.
It's not the only functional language by any means, but it is the strictest (he he.) It's silly arguing which is worth more, but it's also silly saying "Clojure is just as good as Haskell at separating effects."
