I had to think about half a second, and then type for about 8 seconds. Just copy and paste the code and put it in a file that you
require on your projects, and you won't have to think. I will think for you. Matz is busy solving bigger problems and conquering
better obstacles. So he doesn't have to think about this, I will put my brain to work for him.

  class Class
    def attr_class_accessor arg
      instance_eval "class << self ; attr_accessor :#{arg} ; end"
    end

    def attr_class_reader arg
      instance_eval "class << self ; attr_reader :#{arg} ; end"
    end

    def attr_class_writer arg
      instance_eval "class << self ; attr_writer :#{arg} ; end"
    end
  end

If you feel this stronlgy about your desire to simplify this, perhaps you should submit it as an RCR, http://www.rcrchive.net. I
am not saying I think your idea to simplify this into a builtin part of ruby is a bad thing, but I think that you should not
abolish your ability to think. Ruby gives you power, use it. And if you think it can be made better, submit a patch or submit an RCR.

Matz gives you the power to influence the langauge, I challenge you to do so.
