I think the CocoaDevCentral article (1) on bindings is misleading

This implementation would be unacceptable in all but demonstration
implementations.
Out of curiosity, why?
Yep there's nothing wrong with NSDictionary's as the internal storage
mechanism.
The problem is copying the approach that the CocoaDevCentral article
has taken and providing a public NSMutableDictionary [....]
OK, this makes sense, and I agree that it's a problem. But the problem
isn't the use of NSMutableDictionaries (which is why I queried), it is
the lack of encapsulation because of no accessor methods.
(For some reason, writing theoretical posts about object orientation
is *much* more interesting than working on code tonight.)
I reckon! And we won't even start on asking what you meant by a
"theoretical post" ;)
See the lengthy post in which I demonstrated that KVC can be used
isomorphically to message sending. I felt like I was in graduate
school again....
