// Scala's for comprehensions can be used like Haskell's do notation for monadic code, ie. its a compact way to string together computations sequentially. 

val f = for {
  a <- Future(10 / 2) // 10 / 2 = 5
  b <- Future(a + 1)  //  5 + 1 = 6
  c <- Future(a - 1)  //  5 - 1 = 4
} yield b * c         //  6 * 4 = 24

val result = f.get()
