Scala Newbie alert:

basically I'm trying to do something like this: where I pattern match and return a String.

scala> def processList(list: List[String], m: String): String={list foreach (x=> m match{
 | case "test" => "we got test"                                                      
 | case "test1"=> "we got test1"})}                                                  

:10: error: type mismatch; found : Unit required: String def processList(list: List[String], m: String): String={list foreach (x=> m match{

I know I can set a var and return it after the for comp... but that doesn't seem to be the Scala way.
