2.  trait EqualsByRef extends AnyRef

   Implements .equals using reference equality

3.  trait Platform extends AnyRef
4.  final class Ref[A <: AnyRef] extends AnyRef

   Wraps a value such that reference equality holds.

   Wraps a value such that reference equality holds.

   Allows values to be used as map-keys, in sets, etc with uniqueness being by reference.

5.  trait SafeBool[B <: SafeBool[B]] extends Product with Serializable

   Boolean isomorphism.

   Boolean isomorphism.

   Mix into the base type and override this.companion there.

   Examples:

   sealed trait Enabled extends SafeBool[Enabled] {
     override final def companion = Enabled
   }
   
   case object Enabled extends Enabled with SafeBool.Object[Enabled] {
     override def positive = Enabled
     override def negative = Disabled
   }
   
   case object Disabled extends Enabled

   sealed abstract class Permission extends SafeBool.WithBoolOps[Permission] {
     override final def companion = Permission
   }
   
   case object Allow extends Permission
   case object Deny extends Permission
   
   object Permission extends SafeBool.Object[Permission] {
     override def positive = Allow
     override def negative = Deny
   }
