Hmm, maybe.  But to make an equivalent of Gtk2::ListStore::remove you'd
be supposed to update rather than ask the caller to do stuff.

I was thinking something as simple as below (untested).  Like
new_from_arrayref, but taking an iter it should fill instead of making a
new one.  And/or perhaps something to explicitly invalidate an iter by
zapping its stamp, also like what gtk_list_store_remove does.

Set the contents of a Gtk2::TreeIter from the "internal" array
reference representation used by custom Gtk2::TreeModel
implementations.
=cut
void
set_from_arrayref (GtkTreeIter *iter, SV *aref)
    CODE:
        if (! iter_from_sv (iter, sv_iter))
                croak ("expecting a reference to an ARRAY");
