I've had situations where I wanted the code re-use. One place where I've used 
this is where a subclass implements its own #initialize , but also provides a 
separate #initializeFrom: method; both may want to call the superclass 
#initialize to get the superclass instance variables initialized, but 
#initializeFrom: may not want to call #initialize .

Where I've had to do this is when I'm using a framework where I can't just 
refactor the existing code (because I didn't write the framework, and because 
then when a new version came out I'd have to track down all of my changes to 
the framework).

If it was all my code, I'd refactor it, of course. But it's not always mine.
