Scala is a big experiment in functional/OOP integration and the jury's still out. If you don't need objects and the JVM, use Haskell instead: you'll learn a lot more.

Clojure has taken the lisp baton from CLisp and Scheme, if you want macros. But even without them, the underlying semantics for concurrency look promising.

If you need to run websites on the JVM, use JRuby on Rails.
