Subject: introspection question

is there a way for an object to tell you where it was created a la
stacktraces?

I tried to hack it in myself, but it's really slowwwwwww. Here was my
hack attempt. I also wanted each object to tell me the time it was
created which works fine.

class Object
  attr_accessor :mp_created_at
  attr_accessor :origin_trace
end

class Class
  alias oldNew  new
  def new(*args, &block)
    obj = oldNew(*args, &block)
    begin
      raise "force a stack trace"
    rescue Exception => err
      obj.origin_trace = err.backtrace
    end
    #a hack that I need for a reason which I haven't taken the time to
figure out
    obj.mp_created_at = Time.now() unless obj.frozen?
    return obj
  end
end
