How to do it...

1. Create a new project called master-slave with the simple stack template:

        stack new using-closure simple

2. Add a dependency on the distributed-process and distributed-process-localnet libraries in the build-depends sub-section of the executable section:

        executable using-closure
          hs-source-dirs:      src
          main-is:             Main.hs          ghc-options:         -threaded
          default-language:    Haskell2010
          build-depends:       base >= 4.7 && < 5
                             , distributed-process
                             , distributed-process-simplelocalnet

At the time of writing this recipe, some of the dependencies are not resolved through stackage LTS. Add the following to stack.yaml:

        extra-deps:
          - distributed-process-0.6.6
          - distributed-process-simplelocalnet-0.2.3.3
          - syb-0.6

3. Open src/Main.hs. We will be adding our ...
