(can you keep lines under 80 chars, makes things a lot more readable in
many environments)

I don't understand the above. If you agree that it is reasonable to always
require specs, then how do you find the ordering requirements in Ada a
nuisance. Please give an example. if you are talking about the basic vs
later ordering rules in Ada 83, just clarify that this is what you are
talking about, because we all agree on that, and it has been fixed for
years in Ada 95.
