Daniel Sockwell investigated the powers of smart matching in the Raku® Programming Language in two blog posts Let’s try some pattern matching (/r/rakulang comments) and Further thoughts on Raku pattern matching (/r/rakulang comments). Both the blog posts and the comments are food for thought!

Grant reports

Jonathan Worthington reports on the finalization of the Raku Dispatch and Compiler Improvements Grant, and Patrick Böker reports on the Raku CI Grant.

Wenzel’s Corner

Wenzel P.P. Peppmeyer shows an approach to re-exporting functions under a different name in Double Inspiration.

Weeklies

Weekly Challenge #134 is available for your perusal.

New Pull Requests

• Remove a spesh optimization if it has too many deopts (rebased after new-disp)
• Add guard for container descriptor $!of for non-nominals
• [JVM] Unbreak build after merge of new-disp

Core Developments

• Geoffrey Broadwell investigated the feasibility of creating a JIT for the AArch64 architecture, and added the result to the MoarVM documentation.
• Jonathan Worthington added [mono|poly|mega]morphic site counts to the MoarVM profiler and fixed issues with the debug server.
• Elizabeth Mattijsen made sure that $*PERL is only deprecated on future language levels of the Raku® Programming Language.
• And some other smaller tweaks and fixes.

Winding down

On time this week, but a bit smaller on account of it only covering 5 days. With less than 2 weeks to go until the 2021.10 Rakudo™ Compiler release that would make the new-disp work go mainstream. So, check in again next week for more news about the Raku® Programming Language in these exciting times!
