If you are comparing to Go then just regular Haskell has all the same capabilities and more (lightweight threads and communication primitives, plus extra cool stuff like software transactional memory). Cloud Haskell is trying to put it more in the Erlang camp where you can distribute beyond a single process transparently, but I don't think it is well maintained or really production ready.
