I like Scala a lot more than I feel like I should. It’s weird to say that it’s a language that feels too academic while also being heavily used by enterprises. I used it a lot while working at BigCo and there were a lot of times that the language got in the way of getting things done due to the design. But it is really elegant once you understand it. It’s no Lisp, of course, but it feels somehow both pragmatic and academic in getting things done. And for writing Spark, it’s quite expressive.
