An experienced Scala programmer told me that something he's found important is to restrict a Scala codebase to only some subset of Scala features (or approaches). That's because in Scala you have an extreme variety of ways you can tackle most problems, and everyone has a different favorite way, thus, if that is left unchecked, the codebase can quickly become a zoo of many many different language features and techniques. I think of Go as the opposite, for example. I can see how that can be a real challenge, but I, for one, am excited by this aspect of Scala more than any other.
