scala - Pattern-match in function literal -

give pattern-matched anonymous function:

val = list((1,2), (3,4)) val c = a.map{case (x, y) => (y, x)} 

is there way achieve same thing function literal using similar syntax?

val f = case (x,y) => (y,x) val c = a.map(f) 

something better this:

val f = (z: (int, int)) => {   z match {     case (x, y) => (y, x)   } } 

it works if type annotate , surround in {}:

scala> val f: (int,int) => (int,int) = { case (x, y) => (y,x) } f: (int, int) => (int, int) = <function2>
