OK.  I think I've been getting ahead of myself (or of the code) a little
with the #_new suggestion there.

It turns out that there was a qobject lisp type wrapping such a pointer
a long time ago, but it is commented out now, there's no marshalling
code for it anymore, and especially no dispatching code, which you would
need (and never has been)...

At the moment, I think you're right.

As you can tell, I'm still more in "what do I want CommonQt APIs to look
like eventually" mode at the moment with my thinking, and not quite in
"how does it work today" mode.

Perhaps Stas has a better suggestion; at least ISTR that someone
actually worked with those models already.
