Tuple Unpacking in Map Operations

I like the tupled function; it's both convenient and not least, type safe:

import Function.tupled
arrayOfTuples map tupled { (e1, e2) => e1.toString + e2 }

Why don't you use

arrayOfTuples.map {t => t._1.toString + t._2 }

If you need the parameters multiple time, or different order, or in a nested structure, where _ doesn't work,

arrayOfTuples map {case (i, s) => i.toString + s} 

seems to be a short, but readable form.

A work around is to use case :

arrayOfTuples map {case (e1: Int, e2: String) => e1.toString + e2}
