    The only problem about this is:

    class Fruit

       class Seed {
         void SetFruit(Fruit fruit)
         {
           this.outer = fruit;
         }
       }
    }

    class Apple: Fruit
    {
       void AppleOnlyMethod(){ ... }

       class AppleSeed: Fruit.Seed {
         void DoSomething()
         {
           AppleOnlyMethod();
         }
       }

       auto GetNewSeed() { return new AppleSeed(); }
    }

    auto apple = new Apple();
    auto seed = apple.GetNewSeed();
    seed.SetFruit(new Fruit());
    seed.DoSomething(); //what happens here?

I think this.outer is not an lvalue, which solves the problem. It
wouldn't make sense to have it an lvalue, because the object is
specifically created out of the initial outer object.

The last time I checked you could reassign outer ;-)
