[Tour] Case Classes example error

[krisweiss]

There seems to be an error in the Tour of Scala, Basics, Case Classes example.

case class Point(x: Int, y: Int)

val point = Point(1, 2)
val anotherPoint = Point(1, 2)
val yetAnotherPoint = Point(2, 2)

if (point == anotherPoint) {
  println(point + " and " + anotherPoint + " are the same.")
} else {
  println(point + " and " + anotherPoint + " are different.")
}

if (point == yetAnotherPoint) {
  println(point + " and " + yetAnotherPoint + " are the same.")
} else {
  println(point + " and " + yetAnotherPoint + " are different.")
}

Running the code in https://scastie.scala-lang.org/ throws: value + is not a member of Playground.Point, but could be made available as an extension method.

Using a String type as the first argument seems resolves the issue:
println(point.toString + " and " + anotherPoint + " are the same.")
or
println("" + point + " and " + anotherPoint + " are the same.")

I would recommend this be resolved by using a string interpolator (s"...") instead
