Useless sarcasm aside, isn't that an abuse of atomics?

Reference counting an abuse of atomics? It's one of the primary use cases for them.

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, Ivan
