# Better way to write this?

I feel like there is a slightly shorter way to write the foreach part, but I can't recall:
val list = 1 :: 2L :: 3d :: Nil
list.foreach { n =>  n match {    case i: Int => println("Int: " + i)     case l: Long => println("Long: " + l)    case d: Double => println("Double: " + d)     case _ => println("Unknown: " + n)  }}

You should be able to drop the match part:
list foreach {  case i: Int => println("Int: " + i)   case l: Long => println("Long: " + l)  case d: Double => println("Double: " + d)   case n => println("Unknown: " + n)}

Yes, of course. It felt wrong, and it was.
Thanks!
