What is the best way to write the following in Scala? It doesn't look quite right to me – first the forward declaration of the 2 vals, then the long PrintWriter creation line, then thefinallyblock. The only thing that's idiomatic, is the catch block…

val outputStream = Try(fs.create(tmpFile)) val writer = new PrintWriter(new BufferedWriter(new OutputStreamWriter(outputStream.get)))  if (outputStream.isFailure) {   logger.error(s"Couldn't open file: $tmpFile") }  try {    features.foreach {     case (sectionName, modelRDD) =>       writer.append("{" + sectionName + ", " + modelRDD.getNumPartitions + "}")   }  } catch {   case e: Exception =>     logger.error(s"Got exception", e)     throw e  } finally {   outputStream.get.close()   writer.close() }
