    Jon Pretty Retweeted ScalaZONE

    An experiment started by @mandubian and continued by @milessabin a couple of years ago resulted in Scala 3 getting kind polymorphism. I've written a lesson all about it... and for an advanced feature, I think it's actually easier than it sounds.https://twitter.com/scala_zone/status/1382286661158121473 …

    Jon Pretty added,

    ScalaZONE @scala_zone
    We're going to jump ahead to an advanced lesson on ScalaZONE this week: kind polymorphism! We take a philisophical look at higher-kinded types, cover the limitations imposed by the `AnyKind` type constraint, and then delve into a worked example. https://scala.zone/courses/scala-advanced/types/polykinded …

        Thanks Jon! I knew of its existence, but not really why we would want this. But your examples give a lot in insight in possible applications.
