It is not happy cute durable turtles all the way down, it is olestra-leaky abstractions from hell. Whenever I think I want to do some kind of project that works with Java libraries, I day dream that oh I'll use Scala because even thought I don't like a lot of the jumped-the-shark syntax, I do like the idea of at least having a repl and static type checking - and then I am told I have to use either Intellij or sbt, and no matter which one I try it is a living hell of opaque broken crap from hell.
