Not really, your example is trying to assign some special meaning to a Java
class whose value happens to be "false".

Using ".equals" equivalence in something as primitive as an if statement
would not only be inefficient, but lead to some really strange
consequences, since equals is override-able.

(deftype Bob []
  Object
  (equals [this o] true))

(.equals a true)
true

(.equals a false)
true

(= (Bob.) false)
true

(= (Bob.) true)
true

;; What should this do?
(if (Bob.) :true :false)
:true
