 module_function make the method private (i.e. a method which can't be
 called with a receiver) and create a public method for the singleton class

 The book is trying to say this

   module Mod
      def meth
         puts "meth"
      end
   
      module_function :meth
   
      def meth
         puts "new_meth"
      end
   end
   
   include Mod
   
   Mod.meth  # meth
   meth      # new_meth

 if module_function just created an alias, the 2 calls will give the same
 output
