4) you can use the delegation pattern and delegate that method to the 
class that implements it.  I don't see any real benefit for using 
classkit() for this.  When using it to emulate multiple inheritance, 
you lose all the is_a() information on a class, which is one of the 
major benefits of inheritance over delegation.
