Performance wise, is it better to instantiate inside or outside the constructor?

```auto

public class example {
   private var _mc:MovieClip = new Movieclip();
   function example(){
   }
}

```

```auto

 public class example {
    private var _mc:MovieClip;
    function example(){
      _mc = new Movieclip();
    }
 }
 

```
