I would expect that "explain-data" should contain the same "via" entry, regardless of whether it is returned from a call to s/explain-data or if it passed to the printer during an assertion failure.


(s/check-asserts true)
  (s/def :example/name string?)
  (def !ed (atom nil))

  (s/explain-data :example/name 1)
  ;; #:clojure.spec.alpha{:problems [{:path [], :pred clojure.core/string?, :val 1, :via [:example/name], :in []}], :spec :example/name, :value 1}

    (binding [s/*explain-out* (fn [ed]
                                (reset! !ed ed)
      (s/assert :example/name 1))
    (catch Exception e))

  ;; #:clojure.spec.alpha{:problems [{:path [], :pred clojure.core/string?, :val 1, :via [], :in []}], :spec :example/name, :value 1, :failure :assertion-failed}

Expected: The ":via" entries in both cases should the same
Actual: The ":via" entry is empty in the explain-data that is passed to the printer during the assertion failure.
