I use Haskell, and my friends at work use Java. Do you think it could be a good idea to use Haskell with Java, so I could understand and cooperate with them? Is there a a Haskell to Java compiler that's already ready to use?
Besides the other approaches people have suggested, maybe you could use a combination of the Haskell FFI and JNI (Java Native Interface) or JNA (Java Native Access). I have no idea how practical this would be, and it would only work on platforms where you can compile Haskell to native code rather than on any JVM, but if that's OK it might be worth exploring. If you want to call Haskell functions from Java, it seems to me it should be possible to write FFI export declarations for the Haskell functions you want to use from Java, and write a C wrapper to package the exported functions for JNI as if they were native C functions. With JNA you might be able to avoid writing a C wrapper, although I know even less about JNA than I do about JNI. It should also be possible to go the other way if you want to call Java code from Haskell, at least with JNI but possibly not with JNA. Andy
