Subject: get method in Array subclass: where's it defined?

Hi,

Daniel Finnie in another tread help me define a Matrix of essentially
arbitrary dimension as a subclass of Array.   He employs a "get"
method to handle a splat of the subscripts.  I can't figure out where
this get method is defined.  Does anyone have any idea?  Code with
examples follow.

Thanks in advance,
Richard

class Matrix < Array
  def [] *args
    if (args.length == 2) && args[0].is_a?(Integer) && args[1].is_a?
(Integer)
      get(*args)
    else
      super *args
    end
  end
end

m = Matrix[ [10,20,30], [40,50,60], [70,80,90] ];
puts m [0] [1].inspect	#  20
puts m [2] [0].inspect	#  70
puts m[1].inspect	#  [40, 50, 60]
