Ref makes references to values explicit. In Scala, objects may have different equality semantics. For example, case classes always implement structural equality, but ordinary classes not necessarily. To use different instances of the same value in a hash table, all objects must be wrapped. Ref is a simple solution for this and ensures that physical equality is always performed as hashCode cannot be overridden.
