Why doesn't it work?

 def initialize_with(*params)
   define_method(:initialize) do |*args|
     if args.size != params.size then
       raise ArgumentError.new("wrong number of arguments"\
         " (#{args.size} for #{params.size})")
     end
     super() if defined?(super)
     params.zip(args) do |param, arg|
       instance_variable_set("@#{param}", arg)
     end
   end
   return params
 end

The "()" on super clears the auto-passing of parameters.
