Subject: Re: how to read arrary with an array

I do not understand what your problem is.

   array = ['abc', [1, 2], 3.0, Time.new]

You can iterate through the elements (or "slots")

   array.each do |element|
     puts element.inspect
   end

   =>
   "abc"
   [1, 2]
   3.0
   2012-10-02 18:09:14 +0200

Some (but not all) of the objects in the array
have a slice-method for element reference, aka []:

   array.each do |element|
     puts element[0]  if element.respond_to?(:slice)
   end

   =>
   a
   1
