I would have used (for example)
type Axis is (X, Y);
type Coordinate is range 1 .. 8;
type Position is array (Axis) of Coordinate;
as the element type (making some assumptions about the problem!). No
need to have a list as the element if the problem doesn't call for it
(though good to be able to if needed, of course).
