title: ARC equivalent of autorelease?
body: <p>If I have this code,</p>
  
  <pre><code>+ (MyCustomClass*) myCustomClass
  {
      return [[[MyCustomClass alloc] init] autorelease];
  }
  </code></pre>
  
  <p>This code <em>guarantees</em> the returning object is autoreleased.
  What's the equivalent of this in ARC?</p>
