trait OO[O <: OO[O]] { this : O =>
type A <: AA[O]

In pure functional languages, is there an algorithm to get the inverse function?
... "chase" a solution while we explore a design space using "undefined" and "error" during development). A "bottom" x has the type a. It "inhabits" (or is a "value") of every type.
