Direct ivar access to an 'int' ivar is still direct access to > an ivar, when one should presumably go through a property or method. This is also legacy of GCC. I think the rational (at the time) was that it is generally safe to use direct ivar access in all cases except for objective-c pointers (which will have API issues related to attributes of their controlling property). Now that we are moving further away from GCC, I will relax this too.
