It's very difficult to avoid it when thing goes complicating. A may reference B, B may reference C, ... and somewhere, X may reference back to A. If this strategy makes sense for big project, many hackers work with C++ can use it either, as the performance overhead is very low. But in the real world, reference-count based GC just has limited usage. |

And in theory it doesn't fare much better. Proper garbage collection can have better performance, and does the Right Thing.
