   Now we are connected into the remote node, as the prompt shows us,
   and we can access the information and modules defined over there:
 
-      iex(foo@HOST)1> Hello.world
+      iex(foo@HOST)1> Hello.world()
       "it works!"
 
   In fact, connecting to remote shells is so common that we provide

  IEx will also color inspected expressions using the `:syntax_colors`
  option. Such can be disabled with:

      IEx.configure [colors: [syntax_colors: false]]

  You can also configure the syntax colors, however, as desired:

      IEx.configure [colors: [syntax_colors: [atom: :red]]]

  Configuration for most built-in data types are supported: `:atom`,
  `:string`, `:binary`, `:list`, `:number`, `:boolean`, `:nil`, etc.

  If we try to dispatch to `Hello.world`, it won't be available
  as it was defined only in the other shell:

      iex(bar@HOST)1> Hello.world()
      ** (UndefinedFunctionError) undefined function Hello.world/0

  However, we can connect to the other shell remotely. Open up
