Monkey Patch Array!

class Array
  alias :orig_uniq__ :uniq
  def uniq(attr = nil)
    return orig_uniq__ if attr.nil?
    [].tap do |c|
      found = []
      self.each_with_index do |el, i|
        val = el.send(attr)
        unless found.include? val
          found << val
          c << self[i]
        end
      end
    end
  end
end

Is this stupid?
