1) There is a difference between "incompetent" and "poorly trained" or
"inexperienced". A number of extremely intelligent software engineers came
to me during their first (or even second) Ada project with either questions
(how do I do this in Ada) or comments (Ada is terrible; see what happens
when I use this construct!). Many times I would ask back "How would you do
it in C?", and they would immediately answer their own question or counter
their own complaint (Ada allows pointer manipulation, for example, if it is
When I asked why they did not think of that answer themselves, they would
invariably say that they did not think it was the right way to do it in Ada.
A valid point in their favor (and in favor of the "temptation" argument in
general) is that the language definition says nothing about the performance
or suitability of any given construct. And, performance changes with
2) My company used to use a computer language called MAC for rapid
prototypes. Everything was double precision floating point. You did not
need to declare variables (they were implicitly created when first used).
For small analyses, this language was very good. Of course, it was not a
reasonable language for anything large (although it was used for a fairly
major-sized simulation by some very careful people before there really was
anything better), but for a large number of "what if" questions, it was an
I am sure there are many others who would extol the virtues of other
languages (like all the interpreted languages) for similar reasons.
I suggest that it is fine to agree that short-term analyses can be more
efficiently done in C++ (I have no experience with that language, but I am
aware of people arguing the same using Smalltalk as the language). At some
point, however, when the code gets complicated enough, Ada can be shown to
be a more productive language.
