No, ideally it should search the objects in the environment where the
model was defined.  There's no guarantee that this is a grandparent, and
grandparents shouldn't be searched otherwise.  It might be tricky to get
this to work.

What isn't clear to me is whether the current environment should be
searched before the environment where the model was defined or afterwards.
