Erlang's concurrency is probably the most similar (greenthreading, channels, messages) and best out there. Errors are handled nicely via supervisor; you can produce a long running fault tolerant system. Haskell's async[1] solution is very nice too, with the exception restarting processes and fault tolerance isn't really there yet. On the other hand, in Haskell there's stuff like STM, which makes atomic updates to shared memory easy. At the lower level side of things Rust's model is very nice too. You can statically verify that you don't have certain classes of bugs. 1: https://hackage.haskell.org/package/async https://hackage.haskell.org/package/async
