A great tribute to ArrayStoreException, because now you can > get the equivalent failure everywhere, in all your types... True. But if you make them covariant, there's the wildcard thing. Can somebody please explain me whether is it possible to have covariant generics *without* all the corner cases that are often bashed in Java? Also, if I understand your point, we have anyway a runtime check (ArrayStoreException) that in Java is currently unfeasible because generics arent' reified.
