If it is in application scope then it isn't really a singleton.  If it is in application scope that doesn't mean there is only one instance per web app.  It just means that there is only one instance at a time.  There is nothing to stop code from changing the value of "myClass" that is stored in application scope.

What might be interesting is a new scope called SINGLETON.  The rule would be that you can add to the SINGLETON scope but you can't remove or replace anything.  

So you would have:

@In(create = true)
  | @Out(scope = SINGLETON)
  | private SomeClass myClass;

Outjection would only happen if the myClass instance got created.  Would that satisfy your use case?
