IMO, a method should not have to know the name of the class in which it
is defined.  If I change the name of the class, then I must be very
careful to make sure that I also change any code inside the class
definition that uses the original name.  Additionally, if I
cut-and-paste a function from one class to another, then I must also be
careful.

In theory, changing a class name isn't (or shouldn't) be done often, and
I should really consider why I am using cut-and-paste anyway instead of
designing my code properly in the first place.  A wise person once
said, though, that the diffence between theory and real life is real
life.
