I believe that only the singleton_method_added actually does anything.
I guess that's because the only methods you can add to this class are
singletons, and that gets priority.

At least, when I tried method_added, I couldn't get any output.

Like so many things, it comes down to:

   * objects can have singleton methods
   * singleton methods are stored in the object's singleton class
   * classes are objects

It's so lovely, don't you think? :-)
