Maybe

trait Maybe extends () ⇒ Option[Boolean]

This trait is to support Kleenean algebra, potentially in a disjunctive or conjunctive expression. The truth-tables for Kleenean logic can be found here: See https://en.wikipedia.org/wiki/Three-valued_logic#Logics Or you can look at KleeneanSpec to see what the rules are.

The original source and specification for Kleenean is in the LaScala project on github at https://github.com/rchillyard/LaScala
