Beautiful frankness. indeed. One question, though: do you think that this
approach is equally applicable to other areas of science/technology?
  By the way, I see, you are from nsk.su, so you have many scientific
institutions near you. Do they permanently reproduce the same "stable and
solid solutions", not bothering themselves with annoying specifics of
"continuously moving problems"?

Surely. Use Microsoft solutions (if you found them solid and stable), as many
people do, and be happy. And avoid Ada language, because it is designed not
for your programmer's pleasure and happiness, but for dealing with real-world
problems, which are, sad to say, continuously moving.

And what is your guess, why these important things weren't included even in
Ada 95 standard? Do you think that Ada language designers severely underestimated
their importance?
