We've seen several of these sorts of bugs over the years, as we add a method to one of our classes with a natural, readable name, and later Apple adds something to an underlying class with a similarly natural, readable name--and suddenly our already-shipping apps have new bugs that weren't there when we built and tested and shipped the apps.

The scenarios you present are all problems caused by Apple's changes to its frameworks (a case could be made that Apple is breaking binary compatibility?). Rather than adding complexity to the language, I think it would be better if Apple found a way to avoid these problems with its frameworks.

For example, if Apple took the list of all methods added to NSArray in NSFoundation release X+1, could they figure out a way to avoid calling overrides of those methods for all apps compiled against NSFoundation release X?

Best,
