No, the tests are independent of the number of integer types, 'Pos
returns a universal_integer value, so all the comparisons use that type.
If somehow you had an enumeration type with more values than
Standard.Integer'Last, the code would still work fine.
As to your other point, I thought that was the object, to determine
which (sub)CLASS of types a generic formal belonged to, when the generic
used (<>);
