I think you may be confusing the return value of a predicate value (acting as a spec) with the return value of the function passed to conformer.
In the former case a predicate function's return value is a logically truthy value and a return of nil or false indicates the value is invalid. The function passed to a conformer is expected to return either a conformed value or ::s/invalid. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
