I did. You wanted acknowledgement that there are problems for which GC is best solution in C++. I explained why it is never best and likely never anything beyond "barely acceptable".
Do you think that this problem is not equivalent to "how do I allow my dog to make a 'press this button for fart sound' app?"?
Do you have a better solution to reclaiming data structures with cyclic pointers?
Of course, sometimes (most times ?) you can't do this, and you really need a GC.
There is a reason why TAOCP spends a whole chapter on GC IIRC...
