          The Ammonite-REPL is an improved Scala REPL, re-implemented from first principles.
          It is much more featureful than the default REPL and comes
          with a lot of ergonomic improvements and configurability
          that may be familiar to people coming from IDEs or other REPLs such as IPython or Zsh.
