| // Example of how a non-static member function can be used as the "deleter" for a std::unique_ptr via std::bind. | |
| // Note: this approach incurs an additional overhead per unique_ptr object to store a pointer to the deleter | |
| // function, so it may not be appropriate in cases where zero-overhead unique_pts are required. | |
