Problematic `== true/false` boolean comparisons

Reading this thread is a fun blast from the past :)

Optional comparison operators

These operators cause some potential for confusion:     public func <<T : Comparable>(lhs: T?, rhs: T?) -> Bool     public func ><T : Comparable>(lhs: T?, rhs: T?) -> Bool     public func <=<T : Comparable>(lhs: T?, rhs: T?) -> Bool     public func >=<T : Comparable>(lhs: T?, rhs: T?) -> Bool 1. The meaning of T? < T? is not immediately obvious (Why is nil < .some(x) for any x? Personally, my intuition says that Optional should only provide a partial order, with .none not being ordered w.…
