Well written Scala code is fantastic to work with, but it does take some practice and judgement to write well structured readable code. If you're having trouble reading your own code days later perhaps consider the way you're using the language. I'd strongly recommend reading http://www.lihaoyi.com/post/StrategicScalaStylePrincipleofLe... if you're have trouble reading your own code.
I second that. Well written Scala code is simply wonderful to read. You learn so much just by seeing how people solve the problem much better than you. Its probably because Scala is so terse, you get to see the logic behind the code much easier than a language with lots of boiler plate.
