  require 'bezel'

  ANSI_VERSION = '1.4.2'

  class ColorfulString
    X = lib('ansi', ANSI_VERSION)
    #include x

    COLORS = [:red, :yellow, :green, :blue, :magenta]

    def initialize(string)
      @string = string
      reset_colors
    end

    def to_s
      s = ""
      @string.split(//).each do |c|
        s << X::ANSI::Code.send(next_color) + c;
      end
      s << X::ANSI::Code::CLEAR
      reset_colors
      return s
    end

    def next_color
      color = @colors.shift
      @colors << color
      color
    end

    def reset_colors
      @colors = COLORS.dup
    end
  end

Then

  cs = ColorfulString.new("Hello World!")

  #puts cs

  cs.to_s.assert == "\e[31mH\e[33me\e[32ml\e[34ml\e[35mo\e[31m \e[33mW\e[32mo\e[34mr\e[35ml\e[31md\e[33m!\e[0m"

ANSI 1.2.6+ has been fine-tuned to work with Bezel. So even core extensions
work.

  red = "How about this!".ansi(:red)

  red.assert == "\e[31mHow about this!\e[0m"
