If you happen to be on Akka, Scheduler is quite convenient for this:

val system = ActorSystem("mySystem", config)
// ...now with system in current scope:
import system.dispatcher
system.scheduler.schedule(10 seconds, 1 seconds) {
  doSomeWork()
}

There is also scheduleOnce for one-off execution.

The usual warnings about closing over mutable state apply.
