 Well, I don't really know what you want to do, and I've tried to do what
 you want but personnally I'll write it like this

pigeon% cat b.rb
#!/usr/bin/ruby

class SceneObject

   class << self
      attr_accessor :generate
   end

   def render
      instance_eval(&type.generate)
   end

end

def defineClass(name, &block)
   Object.const_set(name, Class.new(SceneObject)).generate = block
end

defineClass("MyObject") do
   puts "render some object #{self}"
end

a = MyObject.new
a.render
pigeon%
 
pigeon% b.rb
render some object #<MyObject:0x401ad1f8>
pigeon% 


 I don't know why but it seems more natural, for me, to have a class
 instance variable rather than try to call #initialize
