I was not challenging the fact to use atomics to refcount.
I was challenging the "Let's refcount since it can be atomic!".
Atomics are a heavy dependency, and they're not free.
In the end, that's still about challenging COW.

Point is I'd hate to hear in a few years that C++ is "that language 
where you have to do atomics to add two 512bits integers".

But I'm probably wrong about all this,
