I guess since obj *is* visible in all the nested blocks, its not 
strictly necessary to do the singleton = self trick--you can always get 
the singleton class from obj using obj.singleton_class:

  class MyClass
    def self.some_method(obj, *args)
      puts "MyClass.some_method:"
      puts "obj: #{obj.inspect}"
      puts "args: #{args.inspect}"
    end
  end

  def define_foo(obj, clazz, method)

    obj.singleton_class.class_eval do
      define_method :foo do
        obj.singleton_class.singleton_class.class_eval do
          define_method method do |*args|
            clazz.send(method, obj, *args)
          end
        end

        obj.singleton_class
      end

    end

  end
