You can specify aliasing explicitly with the restrict keyword. It's used in cases where you have two pointers of the same type that are otherwise allowed to alias each other. For pointers of different types it doesn't make much sense and shouldn't be required, there is just no valid reason, except trying to be a smart ass, for two pointers of different types to alias each other, for generic containers you can use void pointers.
