I can't see how statement and answer(?) are related to the original post… or did I miss that this topic is about partials? :)

That is true… so can we agree that nothing should change now, so that something can be added later? ;-)

I would say there's no doubt that extensions are withhold the common nesting powers of all other, similar constructs in Swift: Classes can be nested, Structs can be nested, Enums can be nested, functions can be nested, protocols… I haven't tried yet, but associated objects are something comparable ;-)
