"No, Ada does *not* support multiple dispatching.  Class-wide operations
are something different."

That's a little confusing. Multiple dispatching, like multiple inheritance,
is a programming paradigm. One can follow this paradigm either by using
built-in features in the lanuage which
directly support the required semantics, or it can be programmed 
using features that are appropriate.

It is in the latter sense that class-wide programming has something to do
with multiple dispatching. If you need MD, then you would use CW operations
to achieve the desired effect.
