I just wonder… Should this be roported to Adobe?

Current code gives a runtime error:

```auto
package {
 import flash.errors.IllegalOperationError;
 public class Singleton {
  private static const _Instance:Singleton = new Singleton();
  private var Helpers:Vector.<Helper> = new Vector.<Helper>();
  public static function get Instance():Singleton {
   return _Instance;
  }
  public function Singleton() {
   if (_Instance) throw new IllegalOperationError("Singleton class is a Singleton!");
  }
 }
}
class Helper {
 public function Helper() {
 }
}

```
