Thanks. I have read everything I could find on this but I think I'm just a bit dense about it. Probably, it's just unfamiliarity with the syntax of Scala as a whole and functional programming in general (or maybe I'm just stupid). Hopefully, at some point the light bulb will come on and this will seem easy. I'll read the blog post.
