I don't really have any major problems with this approach in a component
facility in general. The main issue I have with it for the effort we are talking
about is that it requires those multiple generic instantiations. That was the
complaint with Booch that started this whole effort. If people can live with
those, then my vote is for Booch. Otherwise, I think we are forced to design
things using only independant generic packages.

My ideal component library, like yours, would be much more complex than the
strawman. Heck, it may even be the same as yours. But we aren't shooting for
ideal here. We are shooting for something *simple* that Ada newbies can figure
out w/o much trouble, but which is still usable for most serious applications.

If you can find a way to default things so that there's a way to use it w/ only
one instantiation, I'd like to see it.

(ps. I'm sorry for leaving the discussion for so long. I've been on jury duty
all week).
