/** `Null` is - together with [[scala.Nothing]] - at the bottom of the Scala type hierarchy.
 *
 *  `Null` is a subtype of all reference types; its only instance is the `null` reference.
 *  Since `Null` is not a subtype of value types, `null` is not a member of any such type.  For instance,
 *  it is not possible to assign `null` to a variable of type [[scala.Int]].
