Easy parsing using regexes and pattern matching.
// The variable data could easily be an Iterator from scala.io.Source instance, it will work just the same.
val data = List("Food,Count","Cake,9","Biscuits,2","Cookie,10")
val Parser = """([^,]+),(\d+)""".r
val entries = data.collect{case Parser(food,count) => (food, count.toInt)}

Early implementation of the command line parser in my app server.
sealed abstract class CommandLineItem(name: String, description: String)
case class CommandLineArgument(name: String, description: String) extends CommandLineItem(name, description)
case class CommandLineOption(name: String, description: String, optionName: String) extends CommandLineItem(name, description)
case class PassedInItems(options: Map[String, String] = Map(), arguments: List[String] = List(), hangingOptionName: Option[String] = None)
case class CommandLineOptions(commandLineOptions: Seq[CommandLineOption], commandLineArguments: Seq[CommandLineArgument]) {
def parse(args: Array[String]): Either[PassedInItems, String] = {
args.foldLeft(Left(PassedInItems()).asInstanceOf[Either[PassedInItems, String]]){(workingResult, arg) => workingResult match {
case Left(PassedInItems(options, arguments, hangingOptionName)) => {

Use of the command line parser.
object Server {
def main(args: Array[String]): Unit = {
val serviceName = "appserver"
val managerPortOption = new CommandLineOption("Manager Port", "Manager Port", "managerPort")
val serverPortOption = new CommandLineOption("Server Port", "Server Port", "serverPort")
val options = List(managerPortOption, serverPortOption)
val arguments = List(new CommandLineArgument("Command", "Command"))
def success(options: Map[String, String], arguments: Seq[String]): Unit = {
val serverPort = options(serverPortOption.optionName).toInt
val managerPort = options(managerPortOption.optionName).toInt

Weekly Scala Tip: As indiciated by @mariofusco here: http://twitter.com/mariofusco/status/81308217346506752 we should eliminate throwing exceptions up as much as possible.
scala> import scala.util.control._
import scala.util.control._
scala> Exception.catching(classOf[Throwable]).either{"1".toInt}
res2: Either[Throwable,Int] = Right(1)
scala> Exception.catching(classOf[Throwable]).either{"dave".toInt}
res3: Either[Throwable,Int] = Left(java.lang.NumberFormatException: For input string: "dave")
