This is NOT the same as std::shared_ptr do !
How std::shared_ptr manages cycles?
There is std::weak_ptr to handle cycles.

The only question is how often one need to handle cycles ?
Using GC is probably easier as shared_ptr in some case.
But in many other cases only lightweight and deterministic
unique_ptr is required.
Apparently in Rust one can decide what to use.
Box<T> the same as std::unique_ptr<T> in C++.
Rc<T> is something like std::shared_ptr<T> in C++ but not exactly
the same.
But there are also Gc<T> (Immutable garbage-collected pointer)
and Arc<T> without counterparts in C++ at this time.
