2019.40 Quick Syntaxing

JJ Merelo is the proud writer of the latest Perl 6 book: Perl 6 Quick Syntax Reference: A Pocket Guide to the Language, the Core Modules, and the Community. A book packed with useful information and a must-have for any developer new to Perl 6. Highly recommended! (Safari).

Sub as method

Sterling Hanenkamp shows how to use a sub as a method (/r/perl6 comments).

Perspective and FALLBACK

Greg Donald has published two blog posts in the past week: a personal one about his perspective as an outsider, and a technical one about adding an attribute to a class at runtime.

Perl Weekly Challenge #28

Blog posts with Perl 6 solutions for Challenge #28:

• Perl Weekly Challenge 28: File Type and Digital Clock by Laurent Rosenfeld.
• Perl 6 Binary Clock by Arne Sommer.

Challenge #29 is up for your perusal.

Core Developments

• Ben Davies saw his work of the past months on improving hostname resolution (which is part of his IP6NS grant) finally merged.
• Stefan Seifert fixed an issue in the profiler that could cause a segfault.
• Daniel Green fixed an issue in the profiler with exclusive times potentially underflowing.
• Jan-Olof Hendig fixed an initialization issue caught with valgrind.
• Paweł Murias fixed various issues on the Javascript backend, in preparation for the final report on his TPF grant.
• Elizabeth Mattijsen made all of the Buf.write- methods return the invocant, for easier chaining. And added support for calling these methods on Buf type objects, for easier creation of Bufs from scratch.
• And some smaller fixes and improvements.
