Subject: attr_cast, one a small step for interface techniques

another addition to tomslib/rubylib:

	class Module
	  def attr_cast(names_cast)
	    names_cast.each { |name, cast|
	      class_eval <<-EOS
	      def #{name}
	        @#{name}
	      end
	      def #{name}=(arg)
	        @#{name} = arg.#{cast}
	      end
	      EOS
	    }
	  end
	end

try it out:

	attr_cast :avar => :to_s

will create:

	def avar
		@avar
	end

	def avar=(arg)
		@avar=arg.to_s
	end

enjoy,
