Mich, We use Scala for a large project. On our team we've set a few standards to ensure readability (we try to avoid excessive use of tuples, use named functions, etc.) Given these constraints, I find Scala to be very readable, and far easier to use than Java. The Lambda functionality of Java provides a lot of similar features, but the amount of typing required to set down a small function is excessive at best!
