Many of the answers from 2009 still use the old scala.actors.Futures._, which are no longer in the newer Scala. While Akka is the preferred way, a much more readable way is to just use parallel (.par) collections:

vals.foreach { v => f(v) }

becomes

vals.par.foreach { v => f(v) }

Alternatively, using parMap can appear more succinct though with the caveat that you need to remember to import the usual Scalaz*. As usual, there's more than one way to do the same thing in Scala!
