With only ARC, if two objects reference each other, they keep

But do we need more than that? Translating the question into C++:
what use case wouldn't be covered by unique_ptr and shared_ptr?
Cycles, that is why weak_ptr also exists.
Cycles like that could happen in manual memory management, too. There is
Valgrind for that...
For those that can compile their code under GNU/Linux.
There are lots of OS where Valgrind does not run.
