2019.25 On Toolsets

Damian Conway came out with another blog post about Perl 6 in the past week: Coding with an even fuller toolset, as a follow up on last week’s blog post about tooling. (/r/perl6 comments). It also started a thread on /r/perl. Some excellent reading material again. And there’s a lot more of that this week! But first some multimedia:

Summer slurpies, 3 for a $

Matthew ‘Matéu’ Stephen Stuckwisch also wrote an excellent blog post about Variadic functions in Perl 6, or in other words: how and when to use which slurpies (or not). Recommended reading!

• Ben Davies fixed a memory leak when reading bytes from a socket.
• Jan-Olof Hendig fixed a problem recently introduced on 32-bit systems.
• Paweł Murias fixed an issue with wrapped Javascript functions (on the Javascript backend). And he added basic support for

  use Foo:from<node.js>;

  which should unlock all of node libraries to Perl 6 on the Javascript backend!

• Elizabeth Mattijsen fixed an issue with List.reverse and with the use of Junctions in grep.
• Vadim Belman fixed a type checking issue with a role inheriting from a class. He also fixed a problem with additional containers in exported values.

Winding Down

While suffering from what will be this years first heatwave at yours trulies, it is good to see so many blog posts about Perl 6. While the final blockers for a 2019.06 Rakudo compiler release are being taken care of. See you again next week, hopefully a bit less hot!
