Inspired by the mention of increased number of visitors to the 2021 Raku Advent Calendar (up 180% from 2020), and an article about the cycle of adoption of technology, Steve Roe created a Pull Request for the Raku’s Most Wanted list, which describes a plan to make the Raku Programming Language the tool of choice for the scientist / programmer that is hitting the limits of Python. Hopefully, a Python Perch for all the people working on this in the Rakudo Weekly News, will become a thing!
FOSDEM 2022 Status
The Call for Participation for the Raku DevRoom at FOSDEM 2022 is closed. Andrew Shitov lists the 10 presentations accepted for the Raku DevRoom, and the two that were submitted to other FOSDEM tracks. Looks like an exciting program to be seen on the 5th of February!
Complete Course of Raku
On Wolfram and Mathematica
Tomasz Wegrzanowski did another of their Speedrun blog posts, this time about the regular expressions of the Raku Programming Language. This caused quite some discussion. Specifically because of deciding that the behaviour of
\d in Raku’s regular expressions is a design bug (/r/rakulang comments). But it is good to see such an article about Raku “outside” of the bubble!
Looking forward / backward
Several people looked forward and/or backward at the start of the new year:
Sylvain Colinet continued their series of articles about writing an SNES assembler / compiler / disassembler in Raku: Day 4 -Testing.
- Fishy Accordion
- GPS is smarter – part 2
- GPS is smarter – part 3
- Flashy Enhancements
- Many-Worlds over Copenhagen
- Add and remove
- Then came amphipods…

boolfunctionality, introduced the
$*RAT-OVERFLOWdynamic variable, which governs the behaviour of overflowing
Ratvalues (downgrade to
Num, upgrade to
die), added an
Coolvalues, made creation of
Complexvalues about 30x as fast, added a
:slipnamed argument to
roundrobin(), and added the
.infermethod on any iterable (returning the tightest common type).
