How about Scala?

[coolsunglasses]

Anybody that's made a serious go of FP in Scala (applicative, monad, etc) has found that it's not worth the hassle. It fights you the whole way.

Scalaz?

[coolsunglasses]

I hang out with the Scalazzi and authors of FP in Scala on IRC. Most of them, including the original creator, would rather write Haskell and some are doing just that.

I think Scalaz is a pathway to Haskell. When people start loving Scalaz, they just happen to migrate to Haskell.

You would only choose Scala over Haskell if the pros (having the java library and running under the jvm) outweigh the cons (having the java library and running under the jvm) :-)

I would choose OCaml, but you made a good point. 10 internets for you, sir.
