Self-updating SceneReference type

I was looking into ways to prevent having to load scenes using string/int, because if you rename the scene the string is incorrect, or if the build settings change the int would be incorrect.

What I came up with was a SceneReference class that stores the GUID, gets the correct name, and a PostProcessScene function that auto-updates the name compile-time. All that's required is using it as a public variable, and dragging a scene file onto it. It implicitly casts to string and Object, so you use it directly as input into Application.LoadLevel. For example:

Code (CSharp):

1.  
2. public SceneReference myScene;
3.  
4. void Update()
5. {
6.    Application.LoadLevel( myScene );
7. }
8.  

Here's a link to the unitypackage: http://bit.ly/1uh53fj

The way the PostProcessScene currently works is a little bit of a hassle (get every MonoBehaviour, find all SceneReference fields, update them), so if anybody has any ideas how to do that more effectively I'm all ears.
