The Weekly Challenge

HEADLINES

Welcome to the Week #330 of The Weekly Challenge.

Last week, we received the sad news of the passing of fellow Perl hacker Matt S Trout, also known as MST.

It is a significant loss to the Perl community as a whole. RIP my friend MST.

After two consecutive weeks of low turnout, we finally bounced back, thank you, Team PWC.

The guest contributions as well as Perl and Raku submissions also picked up.

The blog posts are coming along well too.

Happy Hacking!!
