class Fruit

    class Seed {} // Not static, because this.outer is necessary
}

class Apple: Fruit
{
    class RedAppleSeed: Fruit.Seed {} 
    class GreenAppleSeed: Fruit.Seed {}
}

DMD 2.059:

Error: class main.Apple.RedAppleSeed is nested within Apple, but super class
Seed is nested within Fruit
