(do (require '[clojure.spec.alpha :as s]) (import '(clojure.lang ISeq)) (defprotocol Foo (foo [this])) (defrecord Bar [bar] Foo (foo [this] (.bar this))) (deftype Baz [bar] Foo (foo [this] (.bar this)) ISeq (seq [this] `(~(.bar this)))) (s/def ::bar number?) [(s/valid? (s/keys :req-un [::bar]) (->Bar 0)) (s/valid? (s/cat :bar ::bar) (->Baz 0))]) ;[true true] -- You received this message because you are subscribed to the Google Groups "Clojure" group.
