On: Choosing Scala

[p8]

Even better:

  scala> println("5" + 5 + 5)
  555

[adriaanm → p8]

    scala> val pi = "pie!"
    pi: String = pie!

    scala> println(f"Care for some $pi%f?")
    <console>:9: error: type mismatch;
     found   : String
     required: Double
                  println(f"Care for some $pi%f?")
                                           ^

    scala> val pi = Math.PI
    pi: Double = 3.141592653589793

    scala> println(f"Care for some $pi%f?")
    Care for some 3.141593?
