Yes, Ada is an excellent wide-spectrum language, because it can do
low-level stuff well. I agree with Jan though that Ada is fairly low
level, especially when compared with Smalltalk, Common Lisp, Prolog,
Python, Icon, etc.
Robert Dewar wrote an interesting opinion on why Java is a disappointment;
in a nutshell, Java forces you to pay the price of a VHLL but doesn't give
you a much higher level view of programming than C or C++, except that you
get garbage collection.

OK, Java and VB were bad picks as representative HLLs. "Scripting language"
is the right term for VB. Have you programmed in Scheme or OCaml? It is
very different from Ada!

A C to Ada translator is possible too, but its existence wouldn't imply
that C is a higher level language than Ada!
