Sure, nim-lang/threading solves this basically by re-implementing part of arc but using atomics for the RCs instead. That solves my particular problem, but this does not integrate seamless with the rest of arc of course. This is one of the cases where arc could shine, if it were to support this use case natively.
So it seems that Nim still lacks some machinery to solve my original problem then? Are there any plans to integrate some of the nim-lang/threading functionalty in the core language? I understand that making arc do atomic RCs by default comes at too high a price, but I can see a solution where the user could choose for particular refs to make them atomic, with arc supporting this natively?
