So, do you actually get the benefits you're looking for without
compiling explicitly to the 1.8 jvm? Because:

$ scala -version
Scala code runner version 2.10.6 -- Copyright 2002-2013, LAMP/EPFL
$ scalac -target jvm-1.8
scalac error: Usage: -target:<target>
 where <target> choices are jvm-1.5, jvm-1.5-fjbg, jvm-1.5-asm,
jvm-1.6, jvm-1.7, msil (default: jvm-1.6)

So even if you use jdk 8 to compile with scala 2.10, you can't target
jvm 1.8 as far as I can tell.
