Kmett has, I believe, taken on a larger role in Haskell, perhaps officially with FP Complete. At any rate he does mention in one his videos (maybe on www.haskellcast.com) that he is coding less now due to his new obligations, which includes [completely from fallible memory] promoting [read: evangelizing] the language.
>inconsistencies that the average programmer will never even realize exist.
Referring to a presentation by Paul Phillips, an absolute Scala giant, and equating that with what the average Scala programmer encounters in their daily work does not negate my argument...in the slightest.
When you leave Scala and remain on the JVM there is no better statically typed alternative, IMHO. When you leave the JVM, then yes, you can dive into Haskell and experience (compared to Scala) longer compile times, yelp o_O, poor to non-existent (IDE) tooling (just type :t in the REPL to see the inferred type, AKA beginner's joy), lack of an enterprise ecosystem, and yes, purity in all its glory, with a superior type system and quite a friendly community of mostly brilliant minds.
In the end I'd say there's some degree of PITA everywhere, even in Haskell. Just getting my feet wet, maybe I'll learn to love it, but for now, to get shit done in the real world, it's Scala and the JVM.
