      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?
