Oh, I'm a big fan of Haskell! It's definitely a language worth learning. However, if you want a pretty nice but still "dynamic feeling" (as opposed to Java-ish) object system, Perl 6 has you covered there. I'd look at P6 as similar to Scala in that it mixes both OO and FP ideas, but with P6 leaning more towards the OO side than the FP side, with not as much type safety as Haskell/Scala/OCaml but with more type safety than, say, Clojure.

If you're familiar with another OO dynamic language like Perl 5, Python, or Ruby, you can probably get up to speed more quickly in P6 than Haskell, and you can gradually introduce more advanced P6 ideas as your ability grows.

But yeah, I'd still recommend you learn Haskell... and Erlang, and Lisp... and...
