Jonathan Worthington tweeted that they finally found the time and the voice to record the presentation they had planned for the German Perl and Raku Workshop. You can either watch the video and/or look through the slides. It basically touches on these four subjects:
- Where is Rakudo now with regards to macros
- Why it’s time to overhaul the Rakudo compiler frontend
- The design of RakuAST, an AST for mere mortals
- A tentative time-path with milestones
Yours truly is particularly excited about the concept of RakuAST, which should allow building executable code without having to resort to using EVAL, with all of its security and performance implications. Exciting times!
Sterling Hanenkamp redesigned / refactored their ArrayHash module, which originally predated the Great List Refactor, and wrote a very interesting blog post about it.
So you have an idea for a project…
Then this round of Perl Foundation Grant Proposals is the place to be! Make sure that you write your proposal before the April 18th UTC. And if you’re without inspiration, then maybe one of the grant ideas that have been suggested, is the one for you!
The continuing story of …
Andrew Shitov continued to work on the Covid-19 Observer. The “What’s new” page of the past week shows
XLS download options, per capita data, compare countries, among many other new features. And in the meantime Andrew still found time to publish part 1 of Chapter 8 of their compiler book.
RakuDist Web UI
Alexey Melezhik has written a small blog post with an update about their RakuDist project. Exciting stuff for module developers and core developers alike who need to be informed about module failures!
Comprehensive Raku Archive Index
Chloé Kekoa continued working on the CRAI project, allowing reproducible builds of all modules in the Raku ecosystem. Look for example at modules that mimic Perl behaviour.
Remembering Jeff Goff
Dave Rolsky has posted an obituary for Jeff Goff on behalf of The Perl Foundation (/r/perl comments).
David Adler, who was on the same cruise as Jeff, also wrote down his memories of Jeff.

Wow! 13 different authors uploaded a module in the Raku Programming Language in the past week. Pretty sure that’s a record! Looks like the lockdown for many is also inspirational to quite a few! For the rest, yours truly repeats: stay safe, stay healthy, stay helpful. See you again next week!
Jonathan = he and not they
Please note that I’m using genderless pronouns in the Rakudo Weekly News as consistently as possible, because most people tend to (unconsciously) have an opinion about another person if the gender of that person can be determined from the text. A little bit like people assign more value to the opinion of a person in a lab-coat, then from someone wearing jeans. Now you may say, but “Jonathan Worthington” is clearly a man’s name? And “Evelyn Waugh” is clearly a woman’s name? But are they? 🙂

Every time I read your “they” it feels like a punch in my face.
I’m sorry to hear that. But that really is *your* problem. Also note that in German (which I assume you are), it is polite to say “Sie”, which can also be meant as plural. So in that sense, it is not all that different.
