I understand most of this example code I think. I'm confused about the
requirement for "addSlot" though. It's used in:

    http://www.dekorte.com/Software/Lua/Object/Actor.lua

Is it a mechanism to allow a method's scope to be a "derived" object, rather
than the object that the method is defined in?

Is there a document describing this approach to implementing a prototype
object model? 

Thanks very much,
