That's simply not true. Just because a language such as Ada offers
you many feature for many different application areas, it doesn't have
to be complex. If you restrict yourself at the beginning to a subset of
the complete
language you will see that Ada is really not that complex. Actually many
things are done in a more reasonable way than in C/C++ for example.
If you know Pascal or Modula-2, you should not have much trouble to
get used to Ada. If you come from a Fortran-77 prespective then there
might be quite a few new things to learn but that's not different for
C/C++, Java, Oberon-2, Python, Eiffel, ..... .

Do you know those stories ? Alot of that seems to be of the urban legend
type : people that have heard from other people that have heard .....
I think Robert Dewar should be in a position to talk about early Ada
implementation ( see www.gnat.com or cs.nyu.edu: lool for Ada-Ed (:-)
or check www.dejanews.com for Robert's Name (;-)).

You're the one making the claim. Not the comp.lang.ada
So where is your story (;-).
