By *the* Ada guru J.-P. Rosen in Ada-Europe 2001 or 2002. And I seem to =
remember in the ARG discussions also, but I'll have to check.

That's what has been shown. That all those "things" can be done in Ada =
now. With either (yes) access discriminants which some say it's the =
golden nugget of Ada or, my favourite, formal packages. And mixins. And =
combinations thereof.

But please do come up with a new "thing" that cannot be done in Ada now.

"Java-style interfaces" is a poor man's multiple inheritance. I'd love =
to see fully fledged (linguistic) MI in Ada 2005, but *that* is too hard =
to define and implement. So I'm happy without it. But in that case I =
don't want the fake MI either.
