+[note `shared_container_iterator` and its factory functions support both
+`std::shared_ptr` and `boost::shared_ptr` for a smart pointer that holds
+a shared reference to the container. However, the support for `boost::shared_ptr`
+comes at a cost of wrapping it in a `std::shared_ptr` internally. This means
+that when constructing the iterator from a `boost::shared_ptr`, the construction
+will have to allocate memory for `std::shared_ptr` shared state, which may
+potentially fail. It is recommended to use `std::shared_ptr` directly.]
