// From: http://alvinalexander.com/scala/scala-class-object-function-convert-multiline-string-to-list-seq

implicit class QHelper( val sc : StringContext) {
    def Q(args : Any*): Seq[String] = {
        val strings = sc.parts.iterator
        val expressions = args.iterator
        var buf = new StringBuffer(strings.next)
        while(strings.hasNext) {
          buf append expressions.next
          buf append strings.next
        }

        buf.toString.split("\n")
        .toSeq
        .map(_.trim)
        .filter(_ != "")
    }
}

// Now this one works for us:
