12:38 AM Ruby Feature #21700: `IO::Buffer.map`: offset argument is "broken" and needs to be made more useful

I've been using `IO::Buffer.map` on macOS without issues. It's still early days but I wonder why it was failing for you.

06:46 AM Ruby Feature #18035: Introduce general model/semantic for immutability.

Another example where immutability as a concept is useful - configurations that span across fibers and threads: https://github.com/ruby-i18n/i18n/issues/723
In general, it seems like immutability for `Fiber[]` values is a good idea. ioquatix (Samuel Williams)
