Subject: Class-level readers and writers

I've been working with the class attribute shortcuts that Hal introduced 
in THE RUBY WAY:

class Class
	def cattr_reader(*syms)
		syms.each do |sym|
			class_eval <<-EOS
				if !defined? @@#{sym.id2name}
					@@#{sym.id2name} = nil
				end
				def self.~{sym.id2name}
					@@#{sym}
				end
			EOS
		end
	end

	def cattr_writer(*syms)
		syms.each do |sym|
			class_eval <<-EOS
				if !defined? @@#{sym.id2name}
					@@#{sym.id2name} = nil
				end
				def self.#{sym.id2name}=(obj)
					@@#{sym.id2name} = obj
				end
			EOS
		end
	end

	def cattr_accessor(*syms)
		cattr_reader(*syms)
		cattr_writer(*syms)
	end
end

I'm having a problem, however, in that classes that are inherited from 
the ones in which I declare these attrs don't seem to have them anymore. 
  Does anyone know how I can make my declared class attributes get 
inherited?

Thanks,
