Yes, you definitely can Scalify things. But having to write boilerplate facades for every library you want to use in a nice way significantly diminishes the utility of Java compatibility.

I meant to say that this is one of the biggest drawbacks of using Scala (along with slightly immature docs). It has an excellent design; it feels like a much bigger language than Java, yet the Scala spec is a fraction of Java's. It is overall an extremely nice thing.
