Hello,
Common Lisp is simply excellent. A popular implementation is
SBCL, runs mainly on Unix-like systems, with experimental support
for windows. There are also commercial implementations for
Windows, e.g. LispWorks.
If you need to run it on JVM, you can try Clojure. ABCL is the
CL on JVM, but I'm afraid it's not a complete one yet, in some
cases (rare, however) you may miss some features. Clojure is
quite different from Common Lisp, and I don't like that.
