Actually, this is a hack already. (Warning, the parameter order is
1.9 only).

   def self.makeClassWithProp(name, superclass = Object, property)
     c = Class.new(superclass) {
       attr_accessor property
     }
     const_set(name, c)
   end

Is a nice and clean way to get that working. This generates a Subclass
to the Module/Class this Method is defined in.
