Does this code leak? Or does bar delete the second instance of foo? The containers never leak. (If so, it is a bug).

I asked as it wasn't clear to me if the container takes responsibility for deleting the second instance as after all it isn't stored in the container. I understand now that the code is safe though. Thanks for your reply!
