Great!

Well, that's debatable, but I think the rationale for leaving direct 
support for MI of implementation in Ada 95 is still valid, and in a 
language like Ada which has other means of abstraction I don't miss 
it much.

Yes, the idea has been proven in the field.

Hmmm, I'm having trouble getting to this web site. Seems like something on
my end, but neither home nor work allow me to connect. If the site is
actually up, then I'll have to figure out where the problem is.
