There are valid complaints about Scala, but the complaints from all those HN armchair experts are far removed from it. There is nothing useful to be done except making fun of it.
Are you claiming that there wasn't an arity limit on case classes that you could run into through no fault of your own using the Scala web stack? Or just that if you had to diagnose that problem it shouldn't bother you as it isn't a valid complaint?
What would elevate someone from HN "armchair expert" in your mind, such that their complaints were valid? Is it even possible for someone to mention something they don't like about Scala without you immediately dismissing them as not knowing what they are talking about?
