This is an interesting discussion.  I think part of it depends on how
extensively one uses inheritance to deal with variation.  For instance,
using Eiffel, with its (IMO) very expressive facilities for multiple
inheritance, one is likely to use inheritance more than one would in
Ada, which tends to leave a lot of plumbing hanging out to use the same
kind of style.

I had a very interesting experience in this regard only recently.  I
wanted to develop some test suites for a restricted Ada runtime system,
intended for DO-178B Level B applications.  I wanted to use AUnit for
it.  But when I wrote AUnit, I used an Eiffel-style lists package that
was implemented over tagged types: no way was it going to run in that
environment. I decided to try out Charles for the same purpose, and it
worked admirably.  No changes necessary.
