    So, @oxnrtr suggests that :: and +: are the only common uses of right-associative operators. I think parser combinators use them too, but is there anything else?https://twitter.com/propensive/status/1285243712352718849 …

    Jon Pretty added,

    Jon Pretty @propensive
    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)

        foldLeft /: and foldRight :\ come to mind. Though they were deprecated in Scala 2.13
