Arcis not free, and the extra atomic operations + heap allocations can become a bottleneck.Oh, I did not know that. Well, it makes sense that it has a heap allocation, as it becomes more or less global. Though not sure why the atomic operations are needed when the value inside is immutable.
How can you otherwise keep track of an object's lifetime if copies are made concurrently?
