> It looks like {{CacheableBlock}} in {{CachableBlockFile}} has a generic method which overrides a superclass's generic method.
> Type safety cannot be guaranteed by the compiler, because it cannot guarantee that the generic parameters of the subclass conform to the generic parameters of the superclass.
> I'm not sure this is avoidable, and in any case doesn't appear to be a problem in this particular case.
> We can just suppress this particular warning.
