ruby$ ri Enumerable#each_with_index
--------------------------------------------- Enumerable#each_with_index
     enum.each_with_index {|obj, i| block }  -> enum
------------------------------------------------------------------------
     Calls block with two arguments, the item and its index, for each
     item in enum.

        hash = Hash.new
        %w(cat dog wombat).each_with_index {|item, index|
          hash[item] = index
        }
        hash   #=> {"cat"=>0, "wombat"=>2, "dog"=>1}
