Re: [Pyobjc-dev] Key Value Observing of lists?

Hi,

I've just stumbled on this again (I'll be writing a short blog post  
about it when my host is back online). I think I'm a bit confused...

Just to make things very clear, is this not possible even if using a  
Cocoa collection like NSMutableArray and calling Cocoa methods on it  
(insertObject_atIndex_)?

So basically, _every_ method that mutates something that needs to be  
observable must be surround with "willChangeValueForKey_" and  
"didChangeValueForKey_", right?

Is there any shortcut for doing this?
