I wasn't think in terms of this being mutually exclusive with your
desires. Merely raising up the notion that the possibility exists
of creating a sandbox, so to speak, for people to play in, a tool
for the exploration of such concepts.

No, and I wasn't arguing that you shouldn't move forward, either. I
was just stating my personal opinion regarding the utility of simple
OO-ish features, that's all.

Well...that's sorta like saying no research into procedural language
design is needed 'cause now we've got C++.

Whether or not the existing standard for ODBMS is the greatest thing
since sliced bread, I find it hard to believe that no research is
required or design issues raised by the fundamental problems of
database technology.

Maybe I'm wrong, though, maybe the problem's been solved.
