You can write purely functional programs in CL by simply choosing not to use those constructs. Most modern Common Lisps have proper tail call elimination, so you don't need loops. I can think of a couple of issues with Common Lisp that make it less ideal for FP than Haskell, but they don't involve the things you mentioned.
