Example of separation between data and behavior with implicit conversions

gistfile1.txt

SomeData.scala:
case class SomeData(a: Int, b: Int)

AdditionExtensions.scala:
object AdditionExtensions {
  implicit class SomeDataConversion(d: SomeData) {
      def add = d.a + d.b
      def add1 = d.a + d.b +1
      ...
    }
}

some other class:

import AdditionExtensions._
val myData = SomeData(2, 3)
println(myData.add) //5
println(myData.add1) //6
