Well, I guess we're all entitled to our opinions.  Yes, compared to
perhaps Eiffel, tagged types can occasionally be a bit clumsy, but not
particularly compared to C++.  And yes, it is far less error-prone than
..., but certainly no less flexible ;-)

"Bull-Hockey", to quote someone I can't remember.  Aside from various
idioms for common cases laid out in the Ada 95 Rationale, you can do
fully general multiple inheritance using access discriminants (also
described in the Rationale).  It's just that it's a bit more clumsy than
in some other languages.
