I'm quite surprised I haven't run into this sooner, but I seem to have just discovered that there's no means by which you can access the outer Class object once inside the context of the Singleton Class. Take the following example; how would I get a reference to (({Test})) from within the singleton?

  class Test
    class << self
      # How do I get a reference to Test from here?
    end
  end

I assume the answer is that there is no reliable way, hence the reason for this request. Could we add a method to the singleton class that allows access to the "outer" class, e.g.

  class Test
    class << self
      self.outerclass
    end
  end

Thoughts?
