I've only been programming since 1960, but IMHO Ada is much more of a
programmer's
language than is C. At least Ada 83 is; I know 95 only from reading,
which often doesn't convey the full flavor. Please don't confuse
"programmer" with "hacker"; a programmer is concerned with issues of
maintainability and code reuse.

They started us on machine language so that we would appreciate the
assembler, and
ever since then I have felt that the computer should relieve the
programmer of the
grunt work as much as the state of the art allows.

Now, I am not saying that Ada is my favorite language (I prefer PL/I),
or that it is
universal (ICON and SETL do much better in theri respective domains), or
that Ada is
perfect (I could criticize it at great length.) But it *is* very much a
programmers language.

"Execessively" is such a subjective term; while there may be area's
where Ada's type
rules are poorly thought out, there are areas where they could usefully
be tightened.
As for cumbersome, I found C to be far more cumbersome than Ada.

You mean like display buffers? I not only used Ada for that, but my Ada
version was
faster than the assembler version it replaced.
