Jonathan Worthington announced an updated Comma Roadmap. With native support for the Mac M1 processor, more module creation / maintenance support and lots of interesting new debugging facilities. All made possible by those of you buying a Comma Complete edition!

Wenzel’s Corner

my &surprise = Bool.pick
  ?? -> $value { $value * 2 }
  !! -> $value { $value / 2 }
say surprise(42);  # 84 or 21
