--- Comment #4 from Kenton Varda <temporal at gmail dot com> --- > This report entry made me wonder why iterators could not just be > pointing to the node just before the one containing the pointed to value. That's a neat idea. I think there is an obscure issue, though. If I have an iterator pointing at item N, and then I (separately) erase item N - 1, what happens to my iterator? But you bring up another, simpler point: why not just have an erase_after() method like forward_list does? That would suit my use case (although at this point I've rewritten it to do something different).
