That is, if the user declares a property of type _Atomic(_Bool), we should pretend that the property has type _Bool when creating the getter and setter.


That sounds like a more principled way to fix the problem. We'll have to remove _Atomic from return types of normal functions too, not just objective-c getters and setters, because otherwise programs like this won't compile:

  _Atomic(_Bool) foo1() {
    A *a = [A new];
    return a.p;
  }
