[Haskell-cafe] CAL experience

Hello, as this is really friendly forum, I'd like to ask to perhaps solve my wonder. From time to time I'm seeing people here recommending Scala as a kind of replacement for non-existent Haskell on Java/JVM platform. My wonder is: why the people here do not recommend CAL, which at least to me, looks much more closer to Haskell than Scala is. Are there any bad experiences with this language and OpenQuark platform? I'm asking since I'm currently playing with it and plan to use it for java objects data processing. Thanks, Karel
