Randy mentioned a time machine... I don't know, I think that if I could alter the the past (Ada 83) for some = minor alterations it would be to include null-exclusion on access types... = seems like that would have been far more useful in-practice than mucking ab= out with 'Pred/'Succ or 'First/'Last. -- child packages would have been nic= e from the inception, but I don't think the compiler-writers would have tol= erated the added complexity there given that as it was Ada 83 was pushing t= he bleeding-edge bounds of compiler technology.
