This is a more specialized problem. And yes, of course, there has to be
universal index types. For example:
type My_Index is private index;
-- Have to implement 'Succ, 'Pred, 'Range etc
type My_Array is array (My_Index range <>) of Something;
Here index is private, array is public. The most general case is when
everything: index, element, and array are private:
type Item is private;
type Key is private index;
-- Have to implement 'Succ, 'Pred, 'Range etc
type Table is private array (Key range <>) of Item;
-- Have to implement Get, Set, Slice etc.
