I don't get it, just use `list<person>`. The prev and next pointers live next to the person objects right in the same node, no need for intrusive pointer. edit

I don't get it, just use `list<person>`. The prev and next pointers live next to the person objects right in the same node, no need for intrusive pointer. edit: The author assesses that this is somehow bad for person objects that are expensive to copy. But std::list has splicing operations, and since C++11 it has emplace as well, so this doesn't apply.

There's no way to use that optimization if you need to be in two or more lists at the same time.

  Wouldn't std shared pointer handle that case?

    Was it available when ZeroMQ was being planned? It's not a very new project.

      boost shared_ptr has been around since 2001. ZeroMQ was started in 2007.

  Which is also an issue in the author's example, no? So the point would be moot.
