I agree, I was too categorical.

Why? SML, Modula-3 and Ada does not have the notion of inheritance.

I agree, but I fell that in people's mind, the footprint left by c++ is
more for the Object model than for its module system.

I do not agree with you. I would even say the opposite. Smalltalk-80, as
well than Lisp languages (Scheme, CLisp), are very suitable for
designing quickly a prototype. And I believe they are still very good
nowadays. Smalltalk-80 has a very nice debugger, and ___none___ of
environment of C++, Java, C# has a such nice one.
