Why doesn't Function2 have an andThen method?

Question

Why does andThen only exist for single argument functions in Scala?

The following code works:

val double = (x: Int) => x * 2
val timesFou         


        

Answer 1

I have just noticed it is easy to work around with the following:

val multiplyAndDouble = multiply.tupled andThen double
val res = multiplyAndDouble(1, 3) // res = 6
