I think what Ian meant was that a generic unit can be a function, and some
functions are recursive. E.g.:
generic
type Number is range <>;
function Factorial (N: in Number) return Number;
function Factorial (N: in Number) return Number is
begin
if N < 0 then raise Constraint_Error; end if;
if N < 2 then return 1; end if;
return N * Factorial(N-1);
end;
Here the last occurance of 'Factorial' is the use of the generic unit's name
as its current instance in order to make a recursive call upon itself.
