Vadim Belman provided an extensive introduction into Type and Object Composition in the Raku Programming Language. A true Tour de Force! In other words: more than you ever wanted to know about types and objects!

Anton’s Corner

Anton Antonov dived into the Graph representation of grammars.

Khalid’s Corner

Khalid Elborai collected their experience with Nativecall while developing an interface to the SOD library, in Raku NativeCall Notes (/r/rakulang comments). An exciting development!
