Let's say this is the original with pattern-matching:
val s: String = option match {
case None => getValue
case Some(foo) => foo.asText
}
You could write this as:
val s: String = option.map(_.asText).orElse(getValue)
I might have misunderstood, it's just hit midnight and I've had a long
day. If I have, can you give a code example? Tony Morris' cheat
sheet might help; http://blog.tmorris.net/scalaoption-cheat-sheet/
