Or, how to go from Perl v5.005 to Perl v5.32.1 in one step.

I have though several times about trying to reimplement Perl in Rust and every time I quickly convinced myself not to do it. First of all because it is way beyond my expertise. However also, what is the value of it? As I understand it there was a presentation about it at the German Perl Workshop covering the motivation as well. Very interesting. You can read the documentation and see the slides. I am rather excited!

Welcome to a new week with a couple of fun tasks "Count Prefixes" and "Valid Times". If you are new to the weekly challenge then why not join us and have fun every week. For more information, please read the FAQ.

by Mohammad Sajid Anwar (MANWAR)

Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Alphabet Index Digit Sum" and "Valid Token Counter" tasks in Perl and Raku. You will find plenty of solutions to keep you busy.

by Arne Sommer

An informative and thoughtful article which illustrates Raku's fantastic facilities for creating grammars and using tokens to model your own custom alphabet in a pleasing and expressive manner. Good balance of theory with practical approach; gives uncommon parsing concepts reasonable readability as well showcasing Raku's idiomatic implementation.

The implementation of this solution has been done using a clean and organised manner. It shows excellent use of list processing in Raku while also using control flow to solve the problem effectively. Based on the written implementation, the author clearly understands how the system works as shown by their concise and logical reasoning in the code itself, as well as providing an idiomatic means of expressing themselves through the way they wrote their code.

by Jaldhar H. Vyas

A clearly written and entertaining article that clearly shows both Perl and Raku solutions in parallel. This demonstrates the author's understanding of the idioms and strengths of both languages. The article provides clear logic as well as practical examples of how to implement the logic. The information provided in the article is helpful in showing the differences and similarities between the two programming languages, while also being concise and easy to read.

by Jorg Sommrey

This is an intelligently written article that succinctly outlines how to utilise an effective problem-solving methodology without sacrificing either code readability or idiomatic use of language. In addition, the article does a wonderful job of providing clarity as well as technical depth in order to enhance both continuity in reasoning and elegance/instructional value of the solution.

by Lubos Kolouch

This well-written article provides structure to help readers understand how each Weekly Challenge solution was developed. It combines clear explanations with practical examples of code to look at both how to apply a problem and how to solve it. The author demonstrates an understanding of their problem as well as the specific requirements that need to be satisfied in order for a given solution to be considered valid, but also gives the reader a fun place to explore various forms of programming using the languages of Perl and others.

by Luca Ferrari

An organised, well-articulated post that illustrates your consistent, orderly method for completing each week’s Challenge with great success in diverse languages. This demonstrates your problem solving capabilities as well as your versatility. All explanations provided were descriptive and practical; therefore were applicable across all languages. Also, by providing side-by-side examples of the various implementations from different programming languages, you have created meaningful comparisons; therefore illustrating each language’s distinctive characteristics.

by W Luis Mochan

A normalised write‑up is written in an interesting way, making it clear and fun to understand about solving both parts of the Weekly Challenges providing well-structured solutions and Perl/Raku examples. Examples will also be provided that are easy to read, written clearly and concisely, demonstrating logic that can be understood easily, by those with varying abilities.

by Marc Perry

The post is full of energy and fun. It presents a practical, hands-on approach to completing the Weekly Challenge with appropriate justification and effective usage of Perl programming constructs. Solutions demonstrate an excellent understanding of the basics of programming (particularly list and string). Implementation of the solutions are both approachable and educational for the viewer.

by Matthias Muth

A concise README that is thoughtfully organised, with clear explanations and idiomatic code, that makes it easy to replicate your approach. You have demonstrated excellent problem solving and a high level of attention to clarity in your write-up; you have also successfully managed to balance the level of detail and technical depth for other people to follow.

by Packy Anderson (PACKY)

This is a creative solution that is fun, playful, uses a literary reference to solve a technical problem, and has clarity of thought and personality. The implementation is brief and uses idiomatic Perl. The strengths of Perl have been used to make it clear, and the story has been made clear and memorable.

by Peter Campbell Smith

This is a good example of a solid engineering solution. It shows a structured and clear thinking process, as well as how well you have used the basic features of Perl to accomplish the task at hand. Your implementation is both concise and expressive; thus, demonstrating your mastery of decomposing problems into their components and using clean, idiomatic coding methods in your programming experience.

by Reinier Maliepaard

This document has been created in a deliberate and orderly way which shows a good understanding of the problem at hand as well as the logic behind arriving at the answer; it also includes attention to detail when implementing the solution. The solution is practically designed as well as creatively developed and uses Perl features thoughtfully to create an efficient and effective answer.

by Reinier Maliepaard

It is a clear and well thought-out solution that uses a sound problem-solving method, reasoning clearly, and has clean, idiomatic Perl code. The method is easy to implement, efficient and has demonstrated the author's understanding of the problem and their attention to edge cases in the implementation process.

by Robbie Hatley

The post gives a comprehensive introduction to how to use Perl, as well as examples of its many capabilities. Each task has been addressed thoroughly by providing clear explanations and well‑structured code, illustrating the effective and creative use of Perl idiomatic patterns. All of these characteristics make this post an excellent resource for both learning Perl and using Perl as a reference.

by Roger Bell West (FIREDRAKE)

This post presents a clear, thorough examination of the problem and provides an explanation of the solution to the problem through logical analysis. Roger has created a detailed description of the proposed solution, which includes smaller, clearer explanations and code so that all readers, whether looking for Perl or token-based parsing methods, can easily understand how to implement these methods in their own code.

by Simon Green (SGREEN)

A concise write-up, which clearly illustrates the two parts of the Weekly Challenge: counting an index, transforming alphabet position into repetitive digit sums, and validating tokens via concise logic expression, using both Python and Perl along with a clear explanation of the solution with examples of practical problem solving and proper implementation.

It sounds like the German Perl Workshop became a replacement to the mostly defunct YAPC::EU.
