Hi,

Today I stumbled upon the implementation of the category method in  
Class. It performs a lookup to check whether the name stored in the  
instance variable is still correct. I have performed some tests,  
changed the category names back and forth, and it always was correct.  
So what is the purpose of this kind of implementation? When can a  
category name change without the instance variable being set to the  
same value?

I would be very thankful for any hints.

Kind regards,

Thomas
