And then what? Put in checks manually that you could have done in the
first place? As this would be an alternative option, your suggestion
being the only option is not quite true.
Also you have the freedom in C to put in your own checks. Certainly Ada
is easier as it puts them in automatically for you, and will leave them
out for you if you ask it to, but I would not agree with the suggestion
that this functionality gives you *more freedom* than C.
(Not that I think C is better of course :-)
