Yes, thank you for breaking it down. I believe we've isolated the

I don't think this will be difficult for me to implement.

Yes, thank you for explaining that for me.

Well, I see how your example compiles in the case of RAW cyclic pointers.
However, I cannot use raw pointers, and I don't know how to get it to
compile with cyclic smart pointers (specifically, boost::shared_ptr).
Was there something that I missed?

Thanks,
