What do you think about the libraries, documentation, and sample code available for Scala or F#? I think they might have a better chance than Haskell or OCaml, no?
I'm excited by the possibility that these languages will make functional programming mainstream. Clojure's another exciting language. But I had to choose, there're only so many hours in the day, and for better or worse, Haskell is where I am focussing my efforts.
