I'm getting that error message when I try to run this code:
numsList |> List.forEach! \nums -> Stdout.write! nums
https://roc.zulipchat.com/#narrow/stream/231634-beginners/topic/Exclamation.20mark.20for.20List.2EforEach!.20not.20being.20detected.3F.3F
Thanks, I guess I'll try using Task.forEach
Task.forEach
