The one about frequency
Each week Mohammad S. Anwar sends out The Weekly Challenge, a chance for all of us to come up with solutions to two weekly tasks. My solutions are written in Python first, and then converted to Perl. It's a great way for us all to practice some coding.

Perl Weekly #645 - Advent Calendars
In the previous edition Mohammad sent a call to get sponsor for his Weekly programming challenge. Several people replied to me. Those messages were forwarded to Mohammad as that is his gig. However, I noticed that the link we used to have at the top of the Perl Weekly was only showing up on the web site. I added it back. In a nutshell, if you'd like to spoonsor/financially help the work of Mohammad S Anwar then either contact him or just support him via Patreon. If you'd like to support my work then you can do so either via Patreon or via GitHub.

Perl Weekly #644 - Perl Sponsor?
I run The Weekly Challenge project primarily focus on Perl and Raku but open to all programming languages. It was started on 25th March 2019. It has been going on un-interrupted ever since, thanks to the strong 350+ members of Team PWC. We were lucky enough to have solo sponsor, Perl Careers run by Peter Sergeant since July 2019 without break. Initially we had weekly prize sponsorship but later it was changed to monthly sponsorship. The best part was, I didn't have to move a finger to find the sponsor. Pete was generous enough to come forward and continued supporting the project for such a long time.

Perl Weekly #636 - Happy Birthday Larry
I am not sure, if you noticed this but Perl Mongers certificate expired few days ago. I only noticed as one of the contributor to The Weekly Challenge shared link to the site. The very next day, I saw post by Olaf Alders on Twitter talking about it and sharing the tool that can help avoid such incident in future. The certificate has now been restored.

Ask HN: Are you using Raku? Pros / cons?
Oh yes, Bruce Gray was a major influence for me as well a couple of years ago. He often participates in the "Raku Study Group" meetings as well - these are very broad and informal meetings every second Sunday but around the end, Bruce almost always brings up some Raku (sometimes Perl) solutions for the weekly challenges from https://theweeklychallenge.org/. In case you are interested, the repo of the meetups: https://github.com/doomvox/raku-study
Back to the topic. I picked up Raku a couple of years ago and I mostly use it as a better shell.
The pros are that you can really quickly and swiftly deliver CLI automation tools and scripts; the language has a unique but very practical regex syntax, you have very rich tools for string manipulation and you have good utilities to "drain CPU" if you are willing to spend more resources to make something faster (e.g easy multithreading for operations). Also, the language is very pleasant to use, it makes you feel very clever and powerful.
The cons cannot be neglected, however, the biggest problem probably being the performance and stability of the only actually working compiler, Rakudo, and its most functioning bytecode VM, MoarVM. The rich string-processing system and regex engine can be surprisingly slothful if you have vast amounts of text, same for precise bigint and rational computations (which are the default). Not many people understand Rakudo (and especially the VMs) enough to work on bugs or performance improvements, and there are not many low-hanging fruit remaining. Considering this, I'm sad that there has been little strategy regarding getting new maintainers, or having a release strategy besides "we will not change anything that might break code, and just release new compiler versions every couple of months".
Also, I don't know how much this is a con for you but Raku is not a language you can just "learn", you have to explore it and always be ready for a new journey. It's a horizontally huge language with a lot of corner cases you probably cannot all keep in mind. I think I'm managing pretty well but it is definitely a risk; you should probably either find a small subset you are comfortable working with and stick to it, or be okay with exploration using whatever goes, from asking others and reading the docs to investigating the core library inside Rakudo (which is not as bad as it may sound but not everybody wants to do).

Perl Weekly #622 - Perl v5.38 coming soon ...
I had almost forgot about participating The Perl and Raku Conference 2023 because of what I have gone through in the last few weeks and still going on. But the best part is, I have booked everything from air ticket to hotel reservations. Having said, I still have to get the slides ready for the my talk about The Weekly Challenge. If you are planning to attend the conference then please do come and see me. I would love to meet as many Perl enthusiasts as I can. I am mostly looking forward to meet the weekly challenge members. I got exactly 2 weeks time to get everything sorted before it is too late.

The dangers of each in Perl
It's been a very long time that I've made a post that wasn't related to The Weekly Challenge, but it's about time I did :)

What's Wrong with Moose?
You can read about some of the discussions here (that's after the BUILD/BUILDARGS debate). Unfortunately, since much of the discussion took place on IRC, and there's a policy against allowing public logging without explicit permission of the channel owners (I am not an IRC guy, so I'm not one of the channel owners), much of this valuable discussion has been lost to time. I don't wish to repeat this mistake in future projects, but I can't change the past.

Now that the PR for the first bit of Corinna is out, I tried porting one of my CPAN modules to it. It was ... interesting.
I've opened a discussion about revisiting Twigils.

A short tutorial for writing code using the new "feature 'class'" syntax.
However, I wouldn't shelve your plans to put more time into Moose. The PR for the initial Corinna work is out and while /u/leonerduk's work is great, the PR is huge and there are a few minor issues to deal with. I do not know when the initial Corinna work will be finished and even after that, it will be a couple of years before it's considered "stable."

What should I rename MooseX::Extreme to?
It's based on years of experience being the lead designer of the Corinna project and trying to figure out how we can get a version of Moose which is safer and easier to use, including removing a lot of boilerplate. This code:

Unofficial Corinna Update
By now most of you have probably heard about the Corinna project to get modern object-oriented programming in the Perl core. The RFC has been submitted to P5P and it's a slimmed down version of the full specification. It's in seven stages, each building on the last.
-
James Web Space Telescope runs on C++ code.
Then you'll be happy to know that I've submitted an RFC to the core Perl team to introduce a modern OO model to the language. So far the response has been positive and we already have /u/leonerduk who's committed himself to implement it.
