At the risk of sounding like a programming language whore, here’s yet another object-oriented functional language. This one looks less intimidating than Haskell or OCaml, since it is extremely Java-like and claims to interoperate really well with Java code, thereby having the ability to use lots of libraries and avoiding the Achilles Heel of most boutique languages, which are excellent for computing factorials but don’t have any knowledge of the Web (heck, even Awk is Web-enabled these days).
