in scala.collection.immutable
object Set

`object` Set
  `extends` java.lang.Object
  `with` scala.ScalaObject

  This class represents immutable sets. Concrete set implementations just have to provide functionality for the abstract methods in `scala.collection.Set` as well as for `+` and `-`.

  Note that abstract immutable.Set's are not covariant in their type parameter. This is because some subclasses cannot support the `+` method for arbitrary types.
