Re: Source.fromFile(file).getLines

ricky@ricky-desktop:~$ cat test.scala
import scala.io.Source
import java.io.File

object Main {
       def main(args: Array[String]) {
               for (line <- Source.fromFile(new File("test.scala")).getLines)
                       print("("+line+")")
       }
}


ricky@ricky-desktop:~$ scalac test.scala
ricky@ricky-desktop:~$ scala Main
(import scala.io.Source
)(import java.io.File
)(
)(object Main {
)(      def main(args: Array[String]) {
)(              for (line <- Source.fromFile(new File("test.scala")).getLines)
)(                      print("("+line+")")
)(      }
)(}
)(
)(
)

Note that I used print instead of println.  I can't imagine it's a
good thing to have line contain a line terminator of any kind.
