Clojure fills this gap rather nicely, and you can always fall back on Java libraries, if necessary. If you haven't given it a try, I recommend it. Rich Hickey has put a good deal of thought into its design.

Furthermore, you will have a much easier time finding companies that use Clojure than any other Lisp (and where they don't, you stand a better chance of convincing management to allow it at companies that make heavy use of languages that target the JVM).
