//quick hack to pretty-print some text:

 "((hi)(bye(yeah))((x)))".foldLeft(0){ 
    (a,b)=> { 
        var indent=a; 
        b match { 
          case '('=> println("("); indent=a+2; print(" "*indent); 
          case ')'=>println;indent=a-2;println(" "*indent + ")");print(" "*indent) 
          case x => print(x); 
        }
        indent; 
    }
}

prints:


(
  (
    hi
  )
  (
    bye(
      yeah
    )

  )
  (
    (
      x
    )

  )
