There is an interresting paper, "Schizoid Classes", in the september
issue of the ACM Queue magazine, from Rodney Bates, about class and
module semantic beeing merged in Java and C++.

Here is just an excerpt:
"Putting class variables and methods into a class is attempting to make
an object type into both a type and a module. Compared with separate
constructs, it is harder to use for either purpose alone or for both
purposes simultaneously. It adds huge and gratuitous complexity to a
programming language, in a world where most working programmers don't
understand their language, anyway."

And:
"The best-designed languages give you two abstraction tools - a module
and an object type - each of which serves its own purpose reasonably well."

And, unfortunatly, Ada is not even mentioned.
