It is NOT "using all advantages of [a] concept" to insist that
it be used absolutely everywhere. On the contrary, that kind of
approach leads to a much more restrictive and less useful
expressive power.

As for multiple dispatch -- people can disagree -- but I think
the designers of Ada 95 were pretty much unanimous in rejecting
consideration of MD -- it's far too much complexity for far too
little gain. (please note, MD /= Multiple Inheritance -- the
two concepts are unrelated).
