      Given Scala 3's first-class syntax for extension methods, is the complexity of right-associative operators still warranted? Could similar ergonomics be achieved without the magic associativity rule based on a colon in the name? def (x: T) :: (xs: List[T]): List[T] = ::(x, xs)

      Bearing in mind I know absolutely zero APL, are those... precedence weightings?

          yeah. my lockdown present to myself was an APL keyboard and I am basically hanging around on twitter trying to manufacture reasons to whip out a pic of it, like the proud owner of a new kitten Soooo many symbols....pic.twitter.com/ubdECSuNJR

          I've recently switched to using my own implementation of a "split keyboard" to help my sitting posture. Though it's literally just two full-size keyboards plugged in at once. Having done this, I realised I can give them different mappings. I now have a lot of keys to play with...
