Subject: Code explanation requeted

Hi, Can someone please shed some light on the following code:

---
  def test_listen
    s = nil
    log = Object.new
    class << log; self end.__send__(:define_method, :to_int) {
      s.close
      2
    }
    inet_stream do |s|
      assert_raise(IOError) {
        s.listen(log)
      }
    end
  end
---

In particular the "class" statement and "self
end.__send__(:define_method, :to_int)"

Is this actually a class and where is its "end"?

I didn't know you can have a class inside a method. So I'm confused here
as well.

This code is messing up the Ruby parser I'm working on in my IDE.
