Wim Vanderbauwhede continues their excellent blog series on algebraic data types with an extensive treatise on function types in not only Raku, but also Python, Rust and Haskell, with some C and Fortran thrown in for good measure (/r/rakulang, Twitter comments). Recommended if you would like to know more about functional programming and/or algebraic data types!
Continuing RFC investigations
Another collection of cool blog posts this week in honour of the 20th Anniversary of the Perl 6 RFC process:
- RFC 54, by Damian Conway: Operators: Polymorphic comparisons by p6steve (/r/rakulang comments).
- RFC 43: Integrate BigInts (and BigRats) Support Tightly With The Basic Scalars by John Longwalker (/r/rakulang comments).
- RFC22: Control flow: Builtin switch statement, by Damian Conway by Leon Timmermans.
- RFC 190, by Damian Conway: NEXT pseudoclass for method redispatch by Tobias Boege (/r/rakulang comments).
- RFC 307, by Simon Cozens by JJ Merelo.
- RFC 188, by Damian Conway: Objects: Private keys and methods by Alexander Kiryuhin (HackerNews comments).
- RFC 159, by Nathan Wiger: True Polymorphic Objects by Elizabeth Mattijsen
Looking forward to the final three!
Two this time
Wenzel P. P. Peppmeyer wrote two blog posts this week: Guarding Dynamics and Defined or dynvar. Andrew Shitov also wrote two blog posts in the Pearls of Raku series: Issue 5: the
where clause and Issue 6:
BEGIN in addition to the blog posts for the Weekly Challenge.
The entries for Challenge 73 that have Raku solutions:
- Weekly Challenge #73 by Luca Ferrari.
- Sliding Neighbour with Raku & Perl by Arne Sommer.
- Weekly Challenge #73 by Javier Luque.
- Weekly Challenge #73, Video Task #1, Task #2 by Mohammad S Anwar.
- Open the Window Just a Little Bit so Your Smallest Smaller Neighbour Can Get In by Colin Crain.
- Weekly Challenge #73 by Andrew Shitov.
- Min Sliding Window and Smallest Neighbor by Laurent Rosenfeld.
- Weekly Challenge #73 by Jaldhar H. Vyas.
Andrew Shitov reviewed all of the Raku solutions of Challenge #72. The Weekly Challenge #74 is up for your perusal!
- Nicholas Clark fixed a race condition in the garbage collection logic.
- Christian Bartolomäus implemented the
nqp::execnameop on the JVM backend, allowing for a lot of code simplification in Rakudo.
