For 'Access, you have to declare the pointer and the object it's meant
to access on the same accessibility level, i.e. if the pointer is on
library level, the object has to be as well.

For 'Unchecked_Access, the accessibility level checks are suppressed,
i.e. the object is treated as if it were on library level. Then you
are on yourself to prevent dangling pointers. So be careful.
