That’s more like the way NSNotificationCenter works — you specify the target 
and selector, which together act similarly to a function pointer.

I’m not sure why, but KVO uses a single method to deliver all notifications. 
That’s just the way Apple designed it, and KVO is newer than 
NSNotificationCenter so they must have had a good reason for doing so. That 
means the only thing that can uniquely distinguish different KVO registrations 
is the ‘context’ value.
