2017.50 Of Quasi and Injectile

Carl Mäsak reports on the progress of 007, the toy language he is developing as a proving ground for full-blown Rakudo Perl 6 macro support. Check it out if you want to keep abreast of developments in this area. Or even better, want to help Carl and his compatriots in this effort!

Adventing Along

The following advent blog posts flocked our way this week:

• Destructure your Arguments with Rakudo Perl 6 Signatures by Curt Tilmes.
• Five golden rings, Four calling birds, Three French hens, Two kinds of programmers?, And a book review in a Perl tree! (or Rakudo Tree? 😉 by Comborico (comments).
• Test All The Things by Jeff Goff.
• Adventures in NQP Land: Hacking the Rakudo Compiler by Tom Browder.
• HTTP and Web Sockets with Cro by Jonathan Worthington (comments).
• Wrapping Rats by Brian Duggan.
• All the Stars of Rakudo Perl 6, or * ** * by Andrew Shitov.

Core Developments

• Bart Wiegmans fixed a problem in the JIT expression compiler that was tickled by multi-dimensional array slices.
• Samantha McVey improved the Unicode database compiler, aka ucd2c.pl.
• Alex Chen and Paweł Murias worked on fixing an incorrect optimization of || in nqp.
• Zoffix Znet made some meta-operations on Rats 30%-50% faster. He also fixed a generic issue with .tail and the count-only and bool-only optimizations.
• Elizabeth Mattijsen improved the inlinability of several internal methods. She also fixed List.new, which would not decontainerize values when it should, and a bug in multidimensional slices that would not allow Cool values as indices.
• Tom Browder fixed some more issues with regards to tables in pod.
• And a lot of other smaller fixes and documentation and test additions.

Winding Down

Feels like the dark days before Christmas. With a lot of snow, at least for yours truly. Hoping to see everybody again next week for another scoop of Rakudo Perl 6 goodies!
