Matthew ‘Matéu’ Stephen Stuckwisch has written a very nice blog post about the magic that
when can bring to the readability of your code. It got quite some feedback! Even though smart-matching has been a thing in the Perl world for quite some time, the concept of smart-matching seemed to startle many people. See discussions on Hacker News, /r/perl6, /r/ProgrammingLanguages, Facebook and Twitter: Simon Proctor, Jonathan Stowe, Ted Davis, Amjad Masad, The Perl Shop.
German Perl Workshop Videos
The videos of the German Perl Workshop have been uploaded. People interested in Perl 6 presentations, should look at:
- Escape analysis and related optimizations for Perl 6 by Jonathan Worthington.
wheneverby Jonathan Worthington.
- Creating a compiler in Perl 6 by Andrew Shitov.
- Perl 6 one-liners by Andrew Shitov.
- Und goto ist so nützlich by Herbert Breunung (German).

- The Perl 6 Weekly by Elizabeth Mattijsen (Germanish).
French Perl Workshop
In only a few weeks, there will be another French Perl Workshop with the motto “Perl Workshop — Act XV: three languages, three communities, one hackfest, one conference”. Strasbourg is a very nice city, with nice people and a nice venue, so yours truly is very tempted to attend.
Ralph Mellor started an interesting thought experiment to encourage real newbies to programming to try exploration of a language with a simplified Perl 6 syntax, which caused quite a discussion (and a name change from the originally suggested
pyrl). Intriguing 🙂
JJ Merelo reported on his poster about concurrent evolutionary algorithms in Perl 6, presented last April in Leipzig.
Arne Sommer continued his series of blog posts on DIY Cryptography with Perl 6 with Part 5: Real Text. Again, worth reading!
Alexey Melehzik describes how you can automate the interaction with the Azure KeyVault using Sparrow6.
Another call for grant proposals has been made by The Perl Foundation. Please submit your ideas to make Perl 6 better!
Quick Syntax Reference
A new Perl 6 book was announced: Perl 6 Quick Syntax Reference by JJ Merelo. Too bad we will have to wait until November 11 before we can really get it 😦 (Facebook comments).
Starting with the GSOC
Madeleine Goebel describes what she did to come up to steam for her part in the Google Summer of Code in a blog post titled: “Getting Started: Developing for Perl 6“. It provides some very useful links to anybody wanting to get into helping out with Rakudo Perl 6 internals. Looking good so far!
Whatever whenever does
Wenzel P. P. Peppmeyer went a little deeper still into the inner workings of
whenever in Whatever whenever does, inspired by Jonathan Worthington‘s answer to “Is
whenever signal() in
react block order dependent?“.
Perl Weekly Challenge

Challenge #11 is up for your perusal!
- Ticket status of the past week and the month of May.
- Jan-Olof Hendig updated the
libuvlibrary used by MoarVM, to version 1.29.1.
- Jonathan Worthington made entry to all spesh’d/JIT-compiled frames faster.
- Nick Logan made sure some UTF-8 decoding ops are JITted.
- Patrick Böker made sure that
CMPfiles are properly cleaned up on Windows.
- Vadim Belman continued his work on the configuration subsystem. He also fixed some issues related to errors occurring during error reporting and assigning
Nilto scalars with captured types. And finally, all his work in the past months to make
use v6.e.PREVIEWwork, was finally merged!
- Timo Paulssen fixed a problem with the profiler.
- Nick Wellnhofer fixed a problem with sorting 2-element lists with a mapper.
- Elizabeth Mattijsen made the built-in
to-jsonconverter about 60% faster. She also made
List.reverseabout 4x as fast.
