It works ...

I added a column to the model (but not to the view).  The column has
type Gobject.Data.caml, and currently I'm just storing an int in there
(for testing purposes).

The clever/amazing thing is that somehow type inference knows it's an
int, and refuses to allow me to store anything else in there.  Which
is good.
