We had a book with a reading guide. We weren't shown the specs showing
the type of controlled/limited_controlled. So, when you don't have that
information and only know that you can derive from it and then implement
2 or 3 subprograms, you don't need to know about OOP in Ada.
Just like we didn't touch generic packages until much later in the year,
generic subprograms, yeah, because u_d was required early on.

How else would you do controlled types?
