Bidirectional maps between values of two key types.

Format a set of ints into a concise textual description.

Example: "2, 5, 7-14, 20"

Implements .equals using reference equality

Wraps a value such that reference equality holds.

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

Boolean isomorphism.

Mix into the base type and override 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
   }

Fast, efficient lookup functions for static data.

Creation verifies key uniqueness and throws runtime exceptions on failure.
