// I'm very pleased with this rewrite from @jorgeortiz85:

  }

    val emptyMap = collection.immutable.Map.empty[String, Word].withDefault(w => Word(w, 0))
    val counts = words.foldLeft(emptyMap)((map, word) => map(word) += 1)
    val countList = counts.values.toList.sort(_.count > _.count)
    log.info(countList)
