It's a bit disingenuous to talk about Scala without pointing out that the IDE tools are, from my understanding at least, fairly poor when compared with Java's tools. That doesn't mean you shouldn't use it, but if you're trying to convince your boss to use something, totally glossing over a fairly large negative is dishonest. Do the productivity gains from less verbose, clearer code? Probably, but the point is it's not just Java++; it's Java + some very important things - some very important tools, which is a totally different equation.
