Access modifiers

Access modifiers can be augmented with qualifiers. A modifier of the form private[X] or protected[X] means that access is private or protected "up to" X, where X designates some enclosing package, class or singleton object.
package quizful {
   package prof {
      class Executive {
         private[prof] var details = null
         private[quizful] var friends = null
         private[this] var secrets = null

         def help(another : Executive) {
            println(another.secrets) //ERROR
