I like cedlemo's approach.

  def initialize(*args)
    if args.size == 1 and args[0].is_a?(Hash)
      options = args[0]
      area = options[:area]
      renderer = options[:renderer]
      title = options[:title]
      attributes = options[:attributes]
    else
      area, renderer, attributes = args
    end
    attributes ||= {}

    # ...
  end

Thanks,
