This week, Laurent Rosenfeld almost could not write the blog post because of events in the city where they are a council member. Kudos to Laurent for not being stopped by madmen!

Core Developments

  • Stefan Seifert, after many hours of painstaking debugging, fixed a long-standing issue with the interning of parametric types in precompilation. Done as part of the work of getting in-process precompilation to work.
  • Will Coleda documented some nqp:: ops that weren’t properly documented before.
  • Patrick Böker implemented building (on Windows) a rakuw.exe “window” application (as opposed to raku.exe being a “console” application).
  • Elizabeth Mattijsen fixed issues with using set operators with Z and X, and implemented full support for adverbs and partial slices for multi-dimensional arrays and hashes (for v6.e.PREVIEW).
  • Alexandre Jousset fixed an issue with NativeCall and C++ that was preventing instantiating a class more than once.
  • And some other smaller fixes and improvements.
