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. -- Lionel Draghi
