Perl Weekly=20
https://perlweekly.com/
You can read the newsletter on the web, if you prefer.
https://perlweekly.com/archive/756.html
Hi there,
Perl continues to show remarkable momentum in early 2026,
with Dean highlighting the language's improved position in the
TIOBE Index, signaling renewed attention and ongoing
relevance. This renewed visibility is supported by active development and
innovative tooling, from Toby Inkster's
performance-boosting Moose extensions to William
McLean's demonstration of deploying Perl MCP servers on Cloud Run.
Community and ecosystem engagement remain strong, as seen with
CosmoShop sponsoring the German Perl
Workshop and the launch of the Thunderhorse web
framework beta, offering modern features like WebSockets and SSE.
Open-source contributions continue to thrive, exemplified by
Corion's 2025 module releases and Robert
Acock's work on practical data structures, helping developers
build efficient, real-world applications.
The Perl community also places emphasis on knowledge-sharing and
accessibility. Dave Cross's slide archives provide a
wealth of training resources, while the Perl Ad Server
enables easy promotion of community events, jobs, and podcasts,
strengthening connections across the ecosystem.
Finally, discussions within the Perl Steering Council,
such as those on experimental features like refaliasing and declared_refs,
demonstrate ongoing efforts to evolve the language responsibly. Alongside a
growing focus on transparency and sustainability, as highlighted in
Makoto Nozaki's financial analysis of TPRF, these
developments show a community that balances innovation, support, and
stewardship.
Stay positive and healthy, enjoy rest of the newsletter.

Perl Weekly=20
https://perlweekly.com/
You can read the newsletter on the web, if you prefer.
https://perlweekly.com/archive/756.html
Hi there,
Perl continues to show remarkable momentum in early 2026,
with Dean highlighting the language's improved position in the
TIOBE Index, signaling renewed attention and ongoing
relevance. This renewed visibility is supported by active development and
innovative tooling, from Toby Inkster's
performance-boosting Moose extensions to William
McLean's demonstration of deploying Perl MCP servers on Cloud Run.
Community and ecosystem engagement remain strong, as seen with
CosmoShop sponsoring the German Perl
Workshop and the launch of the Thunderhorse web
framework beta, offering modern features like WebSockets and SSE.
Open-source contributions continue to thrive, exemplified by
Corion's 2025 module releases and Robert
Acock's work on practical data structures, helping developers
build efficient, real-world applications.
The Perl community also places emphasis on knowledge-sharing and
accessibility. Dave Cross's slide archives provide a
wealth of training resources, while the Perl Ad Server
enables easy promotion of community events, jobs, and podcasts,
strengthening connections across the ecosystem.
Finally, discussions within the Perl Steering Council,
such as those on experimental features like refaliasing and declared_refs,
demonstrate ongoing efforts to evolve the language responsibly. Alongside a
growing focus on transparency and sustainability, as highlighted in
Makoto Nozaki's financial analysis of TPRF, these
developments show a community that balances innovation, support, and
stewardship.
Stay positive and healthy, enjoy rest of the newsletter.

The post delivers a technically clear explanation of both =
the Kolakoski Sequence and Who Wins tasks with illustrative examples and th=
oughtful insight into simplifying the problem logic=E2=80=94showcasing an e=
ffective balance between correctness and practical Perl coding. The walkthr=
oughs help demystify the challenge specifications and offer useful implemen=
tation perspectives for Perl developers.

The post showcases concise and effective Perl implementati=
ons for both the Kolakoski=E2=80=91Sequence and Who=E2=80=91Wins tasks, wit=
h a compact self=E2=80=91referential sequence generator and a structured pl=
ayoff progression model. The code is thoughtfully organised and demonstrate=
s practical mastery of sequence construction and game logic within Perl=E2=
=80=99s syntax.

The write-up presents a thoughtful multilingual exploratio=
n of the Kolakoski challenge with clear logic and practical code that demon=
strates command over sequence generation and problem constraints, making it=
both accessible and instructive. Packy=E2=80=99s commentary and stepwise a=
pproach enhance readability and offer valuable insights for anyone tackling=
the Weekly Challenge tasks.
