title: Did Objective-C get more liberal? Dot notation for non properties
body: <p>I've noticed that I can use dot notation in iOS 5 beta/XCode 4.2 beta, even for methods that are not properties, like <code>Singleton.instance</code> when the method signature is merely <code>+ (Singleton*) instance</code>. If I recall correctly, I couldn't do this in XCode 4.1.</p>

  <li>Has this really changed, or have I gone mad?</li>
  <li>If it has changed, where's the change documented?</li>
