 This is with ruby 1.7

pigeon% cat b.rb
#!./ruby

class SceneObject
   def initialize(&generate)
      @generate = generate
   end
   alias init initialize

   def render
      instance_eval(&@generate)

def defineClass(name, &block)
   Object.const_set(name, Class.new(SceneObject)).instance_eval do
      define_method(:initialize) { init(&block) }
   end
end

defineClass("MyObject") do
   puts "render some object"
end

a = MyObject.new
a.render

pigeon% b.rb
render some object
