     Hello,

  Strange - works as expected for me:

Welcome to Scala version 2.11.7 (Java HotSpot(TM) 64-Bit Server VM, Java
1.7.0_79).
Type in expressions to have them evaluated.
Type :help for more information.

scala> var compactWay = Array("I", "like", "this", "way")
compactWay: Array[String] = Array(I, like, this, way)

scala> compactWay(0) = "We"

scala> println(compactWay.mkString(" "))
We like this way

scala> var secondList = Array("Something else")
secondList: Array[String] = Array(Something else)

scala> var thirdList = compactWay++secondList
thirdList: Array[String] = Array(We, like, this, way, Something else)

     Best, Oliver
