Yes, they already have a reference (self.__class__). The problem is that  
__del__ references Person by *name*, and that name is reset to None (like  
all other module globals) as part of the interpreter shutdown sequence.
Using self.__class__ would avoid this particular bug, but in general, it's  
better not to rely on __del__ at all.
