I have a Seq[Option[String]], let's say the values are surnames to be used
in a mail merge. If we don't know the surname then we just want to "print"
an empty string in its place:
val surnames: Seq[Option[String]] = ...
val default = ""
val surnamesForMerge = surnames map {_ getOrElse default}
I don't know that any given entry will never be None, but I *do* know what
default I want if it is.
