Steve Roe blogged about the union of Raku and Rust in: Option-Some-None, which also touches on a lengthy debate on the essence of nothing (/r/rakulang comments).

Anton’s Corner

Anton Antonov published the Mathematica notebook used for their presentation at the Raku Conference (/r/rakulang comments).

Wenzel’s Corner

Wenzel P.P. Peppmeyer was inspired by Steve Roe‘s last blog, to think about ways of defeating definedness (/r/rakulang comments).

Kay’s Corner

Kay Rhodes, as a learning excercise, presented the new Definitely module in a post on Reddit. Comments / suggestions welcome!

use PHP::Serialization:from<Perl5> <serialize unserialize>;

my %a = a => 1, b => 2;     # {a => 1, b => 2}

my $php = serialize(%a);    # a:2:{s:1:"b";i:2;s:1:"a";i:1;}

my %b = unserialize($php);  # {a => 1, b => 2}

Inline::Perl5 (which only needs to be installed to allow :from<Perl5> to work) is a simple way to access the vast library of Perl modules on CPAN (currently there are 208,288 modules listed).

This “Did You Know” suggested by Steve Roe in the new “did you know” registry, started by Wenzel P.P. Peppmeyer. Suggestions as Pull Requests welcome!

Winding down

Looks like vacation has reduced the number of new and updated modules. Which is also a good thing: burn out should be avoided at all cost!

This week’s image background continues to remind us to support Ukraine in their and our fight against the Russian aggression. Слава Україні!  Героям слава!

In the meantime, please stay safe, stay healthy, keep up the good work!

If you like what I’m doing, committing to a small sponsorship would mean a great deal!
