I too suggest that Scala is worth learning, coming from Haskell. The integration of OO with FP that Scala achieves is magnificent, and any future mainstream language will be measured against it. I would also argue that Scala, which has been influenced heavily by Haskell, improves on Haskell in some domains, in particular, modularisation and generic programming facilities. And then there's the JVM.
