I use Scala for e.g. running Hadoop map-reduce jobs or building REST endpoints. I’d never write a reusable library in Scala though for the reasons pointed out in the article, binary compatibility is not something Scala cares about. I’m never going to use a library written in Scala for the same reason, plus chances are I’d have to spend hours fiddling with SBT to rebuild it at some point. Scala (with Maven) at the top please, then Java all the way down thanks.
