That example does not need `Ractor`.
Yes, you are right, it actually doesn't need Thread either, and is simply about calling a block in a loop and how to break the loop from the called block: `proc { break 3}.then { |p| loop { p.call() }}` raises exception, and `proc { raise StopIteration, 3 }.then { |p| loop { p.call() }}` returns `nil`, etc. ---------------------------------------- Feature #20444: Kernel#loop: returning the "result" value of StopIteration doesn't work when raised directly https://bugs.ruby-lang.org/issues/20444#change-108134 * Author: esad (Esad Hajdarevic) * Status: Feedback ---------------------------------------- There was a https://bugs.ruby-lang.org/issues/11498 a while ago which was merged in, but I was surprised to find out that raising `StopIteration` in a loop like `loop { raise StopIteration.new(3) }` returns nil and not 3. -- https://bugs.ruby-lang.org/
