Vadim Belman has extensively reviewed the way Roles work in Raku, and came to the conclusion that quite a lot of work would need to be done on them to make them fully accessible and malleable from a MOP perspective. And they did that lot of work. This work of the past months has now been merged. Kudos to Vadim Belman for this extensive and intricate work!

Stuart J Mackintosh has blogged about his first 100 days as president of The Perl Foundation, in which he touches on the renaming process and the future of Perl and Raku.

PSA: the next issue of the Rakudo Weekly will be published early on 24 December, rather than 23 December. That will be the last issue of 2019. The first issue of 2020 of the Rakudo Weekly News will be published on 6 January.
