Right. That's what we were trying to do for Ada 2005, and it just didn't 
work out. It's weird that you can default initialize a component in an 
aggregate with <>, but there is no way to do that for an entire object. We 
also wanted to be able to default initialize the private part of an 
extension. But we ran into all kinds of weird problems. I don't plan to go 
there again myself, there were enough people who didn't like anything 
involving "others".
