Subject: Struct-like behaviour in custom classes

Hi,

How can I build a Class that works like the built-in "Struct" and returns  
new anonymous classes based on arguments to MyClass.new?

A simplified example:

   with_foo = MyClass.new(:foo)
   one = with_foo.new
   one.foo

   with_bar = MyClass.new(:bar)
   two = with_bar.new
   two.bar

I tried to do:

   class MyClass
     def self.new_class(method_name)
       c = Class.new(self)
	c.class_eval do
	  define_method(method_name) { puts "method #{method_name} called" }
	end
       return c
     end
   end

How can I rename 'new_class' to 'new' without breaking 'new' in derieved  
classes?

Thank You,
Levin
