I would like to retain the intersection iterators (unless it's too late...). As far as I can tell, if all you have is a Grid g and a codim 0 Entity e,
instead of e.ileafbegin() I would have to call g.leafView().ibegin(e). Won't this be inefficient? In some cases I could pass a view to my function instead (and for that case I agree that using the GridView::ibegin() method is an improvement), but if I also need to call Grid methods, I need to pass the grid and store/cache the view separately for efficiency reasons.


PS. I get your point Christian, and realize the point I argued was mistaken. Thanks.
