 
   To show all entries, configure the limit to `:infinity`:
 
-      IEx.configure [inspect: [limit: :infinity]]
+      IEx.configure(inspect: [limit: :infinity])
 
   See `Inspect.Opts` for the full list of options.
 

  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

  For example, take the following `.iex.exs` file:

      # Load another ".iex.exs" file
      import_file("~/.iex.exs")

      # Import some module from lib that may not yet have been defined
      import_if_available(MyApp.Mod)

      # Print something before the shell starts
      IO.puts("hello world")

      # Bind a variable that'll be accessible in the shell
      value = 13
