Leaves me wondering whether I should hardcode all properties (82 items) on my

Or maybe a composite object?
If the requirement is simply to distinguish between an uninitialised value and
a real value, why not just implement your own object with a method
-valueForKey: and do whatever you want in there. It could have a
NSMutableDictionary as a backing store. One method (not 82) and problem solved.
Sounds so simple I'm surely missing something....
Seems so :) I just tried that and observing the change of properties is
now non-functional, as the request for observing is not forwarded to the
NSDictionary behind my own object. Seems I've to override a whole lot of
methods to forward them all to the backingstore.
