Redundant new and val keywords usage in the 'Operators' section of the Scala Tour #1443
Description
From the Operators:
case class Vec(val x: Double, val y: Double) {
def +(that: Vec) = new Vec(this.x + that.x, this.y + that.y)
}Since case classes do not require the val keyword for parameters of case class primary constructor and do not require the new keyword to create an instance of a case class, the example above could be simplified as follows:
case class Vec(x: Double, y: Double) {
def +(that: Vec) = Vec(this.x + that.x, this.y + that.y)
}
