ETS table creation error

I've run into a problem when trying to create and ETS table based on records. The code is taken from the book Introducing Elixir.

Here's the record:

defmodule Planemo do
    require Record
    Record.defrecord :planemo, [name: nil, gravity: 0, diameter: 0, distance_from_sun: 0]
end

Now if a table is created as follow, it succeeds:

planemo_table = :ets.new(:planemos,[:named_table, {:keypos, Planemo.planemo(:name) + 1}])

In another example, the author uses the following syntax (__record__) and it fails:

planemo_table = :ets.new(:planemos,[:named_table, {:keypos, Planemo.__record__(:index, :name) + 1}])

Error:

** (UndefinedFunctionError) function Planemo.__record__/2 is undefined or private
    Planemo.__record__(:index, :name)
    planemo_storage.ex:6: PlanemoStorage.setup/0

I first thought that maybe __record__ was deprecated in Elixir 1.3.2, but I've not been able to find any trace of it. Please help.

That book seems to be very old. Many of the Records features including __record__ were removed on 24 May 2014 and the change was part of Elixir 0.14 which was released on 17 June 2014.
