Well, I've created "pv_reader", "pv_writer" and "pv_accessor":  XDD

	def self.pv_reader(name, method)
		module_eval %{
			def #{name}
				#{method}
			end
		}
	end
	def self.pv_writer(name, method)
		module_eval %{
			def #{name}= (value)
				#{method}=(value)
			end
		}
	end
	def self.pv_accessor(name, method)
		self.pv_reader(name, method)
		self.pv_writer(name, method)
	end


So I use them as the following:


  pv_accessor :fd :"from.domain"


Ruby is great !!!
