As for underscore being reserved, I have never been able to figure out any consequence of a conflict with an Apple ivar name. It may cause your source to fail to compile, but it won't cause any *binary* compatibility problems, which is the real menace.
I *think* the problem here is introspection... if you subclass an Apple provided class and add an instance variable with the same name as one of theirs, it's possible that any of the dynamic mechanisms the frameworks (or, for that matter, your own code) use to get the value of an object property might use the wrong variable, with unexpected results.
