パターンマッチの網羅性チェックとifガード節
scala> def func(s:Option[String]) = s match{case Some(x) if x.size > 0 => x}
func: (s: Option[String])String
scala> def func(s:Option[String]) = s match{case Some(x) => x}
<console>:7: warning: match may not be exhaustive.
It would fail on the following input: None
def func(s:Option[String]) = s match{case Some(x) => x}
^
func: (s: Option[String])String

scalaz-streamsのTask.startは、既存のTaskの実行Threadも変更できそう
