Hi there, We all know the loss of brilliant mind, Matt S Trout. I am still recovering from it. RIP, my friend. Every time I come across this: *1983 - 2025*, it reminds me of my birth year *1975*. MetaCPAN seems to be running smoothly as shared in this post by Dean. Anyone interested in the work done can find the documentation here. The recently concluded The Perl and Raku Conference 2025 videos are now public on YouTube. Of all of them, one of my favourites is the talk about Dancer2 by Jason Crome. As you know, we had the development release Perl v5.42.0-RC1 on June 25, 2025. In case you missed it, here is the delta page listing all the changes in the release. A week later, we had the maintenance release Perl v5.42.0 on July 3, 2025. Again, we have a dedicated delta page for this release. What's your favourite change in this release? For me, I liked the support for lexical method in the experimental class feature. I'm aware, there are many other importants improvements and bug fixes as well. A big Thank You, to Perl Development Team. What's next in the pipeline? Well, if you ask me, I'm still waiting for support for roles in the experimental class feature. I've heard some whispers that it's in the pipeline. I'm glad it has not been pushed aside. I'm hoping the next stable release will bring good news, fingers crossed! What are you working on these days? I'm mostly working on AWS related services these days as my day job revolves around them. I'm super excited to be working under the guidance of Andrew Solomon from GeekUni. Whenever I explore something new, I create a public post about my experience, viewing it through the lens of Perl and Python. It's not always about AWS, my last post was about Lexical Method in Perl v5.42. I know, it's been nearly a month now but I'm currently working on a blog post about AWS Lambda. My experience so far has been a bit mixed. The native support for Perl in AWS Lambda is not as robust as Python's. After spending a few nights on it, I finally gave up. I'm happy creating lambda function in Python and then calling them programatically from Perl and Python. The most fun part is when the lambda function is stored in an S3 bucket. Then there's another twist, using APIGateway to call lambda function. I use LocalStack (the free version) as a local platform. Unfortunately, the free version doesn't have all the features enabled, but it's still good enough to get my hand dirty. My go-to CPAN module for all AWS related services is Paws. I must admit, it's been rock solid. Apart from AWS, I'm also working on blog posts about DBIC, ElasticSearch, Caching and Serialisation in Perl. Some are nearly finished, they just need a final touch-up before going public. You can track all my experiments on my personal blog page. I noticed a nee section titled "Sponsors" added to the newsletter by Gabor. It did the trick for me and brought in one additional sponsor last week, taking the total count to 35 sponsors. I'd like to take this opportunity to thank each and every sponsor for their generous support. Thank you, Gabor for the initiative! Enjoy the rest of the newsletter and take extra care of yourself.

by Mohammad Sajid Anwar (MANWAR) Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Clear Digits" and "Title Capital" tasks in Perl and Raku. You will find plenty of solutions to keep you busy. |
|
|
by Ali Moradi Both solutions demonstrate excellent Perl idioms. Compact yet readable and good test case coverage |
|
by Arne Sommer Clear explanation of Raku’s built-in methods (words, tc). Demonstrates both high-level and low-level solutions. Also includes tests to ensure correctness. |
|
by Jaldhar H. Vyas Clear, idiomatic solutions. Effective demonstration of Raku's modern features. Practical examples with immediate applicability. |
|
by Jorg Sommrey Production-grade error handling. Empirical performance data. Thoughtful delimiter selection and comprehensive test coverage. |
|
by Luca Ferrari Clear regex pattern using character classes. Clean ternary operator usage. Proper string manipulation methods (tc, lc). |
|
by W Luis Mochan A great post for Perl veterans who appreciate terse, clever code. Beginners might struggle without comments. |
|
by Matthias Muth The step-by-step examples for both tasks are excellent and make the logic easy to follow. The rationale for using regular expressions is well explained and the commentary on loop construction demonstrates good code readability practices. |
|
by Packy Anderson (PACKY) The post shines with its regex elegance and Perl idiomatic style, great for anyone looking to level up their one-liner skills. A bit of reinforcement with edge-case handling, explanatory tests, and clarity amplifies the educational value significantly. |
|
by Peter Campbell Smith The while loop with a regex and substitution is concise and works as intended. Clever way to remove the last character from the matched non-digit portion. |
|
by Robbie Hatley Solutions are practical and well-reasoned. Great for learners due to clear problem breakdowns. |
|
by Roger Bell West (FIREDRAKE) Solutions are concise and readable. Emphasizes immutability and expressive transformations. |
|
by Simon Green The post offers clean, practical solutions in two languages making it both educational and accessible. |
|
by Simon Proctor A well-written, idiomatic Raku solution that highlights the language’s strengths—typing, dispatch and string manipulation while remaining readable and well-tested. |
|
by Yitzchak Scott-Thoennes Goes beyond coding to dissect problem ambiguities, rare in challenge solutions. Provides multiple implementations to handle edge cases. |
