Conceptualizing the world as a set of interacting objects, has ever be
en the main mechanism of perception associated with humankind. Therefo
re, the formulation of languages and modeling and design methods based
on object orientation (OO) was just a matter of time. After that, a m
utual feedback driven process lead to more and better implementations
of OO languages as well as to proven OO based techniques for design an
d modeling. Of course the success of the whole model is related to the
analysis of the adequacy of the actual OO languages for the implement
ation of OO designed systems. This paper reports the results of a simp
le experiment formulated to find some heuristics associated to the ade
quacy of the languages C++, Eiffel, and Ada 9X for the implementation
of OO designed systems.
