Ruby compact only compacts one level deep

My simple solution... recursively remove nil. Kinda lame but oh well.

  #
  # Recursively clean nils out of our array structures...
  #
  def arrayDeepCompact(array)
    array.each do |element|
      if element.kind_of?(Array)
        element.compact!
        arrayDeepCompact(element)
      end
    end
  end

Or if you prefer an extension

#
# Recursively clean nils out of our array structures...
#
class Array
 
  def deep_compact()
    dc(self)
  end
 
  private
 
  def dc(array)
    array.each do |element|
      if element.kind_of?(Array)
        element.compact! #compact first so won't need to itter over nil
        dc(element)
      end
    end
  end
 
end
