  Now, try to access the hello variable again:

      hello

  The command above fails because we have switched the shells.
  Since shells are isolated from each other, you can't access the
  variables defined in one shell from the other one.

  The user switch command menu also allows developers to connect to remote
  shells using the "r" command. Keep in mind that you can't connect to a
  remote node if you haven't given a name to the current node
  (i.e. Process.is_alive? must return true).
