In Java, I can assume that other developers took an OO approach, even if that isn't ideal. In Clojure, I can assume that they took a functional approach. In Scala, it is hard to be sure.

So, is the increased expressiveness worth the decreased predictability? For one developer, it probably is worth it. For a large team distributed over space and time, it probably isn't, even if everyone is comfortable with each individual paradigm.
