the problem i see with this recipe is that the author only tested his code by printing the values which causes __getattr__ to be called with '__str__' and work correctly. but, if you were to remove the print statements and just do a v + v, __getattr__ won't get called as he expected and the join will never happen. i think by making __coerce__ as smart as __getattr__ this recipe would work. can someone validate that i'm correct in what i'm saying?
i'm also curious if it's possible to write this recipe using the new class style for the Deffered class. it appears you can nolonger delegate all attributes including special methods to the contained object by using the __getattr__ or the new __getattribute__ methods. does anyone know how to port this recipe to the new class style?
