The only problem about this is:
class Fruit
{
class Seed {
void SetFruit(Fruit fruit)
{
this.outer = fruit;
Setting to pseudo variable 'outer' should be rejected in
compilation.
Please report it to bugzilla.
}
}
}
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 will not report this, beacuse it will break my custom new operator
(template) for inner classes ;-)
Kind Regards

That's most unwise, because if it's not supposed to be like that it will
get fixed anyway, so you better start replacing your custom new operator.

Replacing my custom new operator exactly by what? Overloading the build
in new is deprecated...
class C{
class D{
}
}
void main(){
auto c = new C;
auto buf = new void[__traits(classInstanceSize, C.D)];
(cast(byte[])buf)[] = typeid(C.D).init[];
auto d = cast(C.D)buf.ptr;
static if(is(typeof(d.__ctor()))) d.__ctor();
enum offset=d.outer.offsetof;
static assert(offset%C.sizeof==0);
(cast(C[])buf)[offset/C.sizeof]=c;
assert(d.outer is c);
}
