Hi, I have started again to do one absolutely trivial improvement every week-day. The idea is that this is something that can be done in <15minutes, the right thing to do when stuck with other work or as the first or last thing of the day. I will do one per day and put another one on the issue tracker for others to do. Today: withAllSubclassesDo: and withAllSuperclasses can be implemented a little bit nicer: https://github.com/pharo-project/pharo/pull/3629 (review needed!) new issue (for someone else to submit a PR): small cleanup traits in Behaviour: isComposedBy: move to traits https://github.com/pharo-project/pharo/issues/3630 The âevery dayâ might be a bit too much, other frequencies could be âevery weekâ or âevery monthâ or âone for every releaseâ I think the âone for every releaseâ is something everyone on this list should have as a minimal goal. We have a list of simple things to do here: https://github.com/orgs/pharo-project/projects/8 Marcus
