I know I don't have to tell you that it certainly confused me. I was quite
stunned when I first saw that you could add methods to a js object.
However, as you don't have access to the source of those classes I can
understand why some consider it a whorthwhile feature.
However, in the case of php where you do have such access it seems ludicrous
to me to do such a thing. If someone wants to add additional functionality
to a php object, why not simply write it into the class? Treating them as
if they are compiled objects seems more than a little silly to me.
