錯誤類型仍然使用clojure core.typed編譯嗎？

Question

項目文件：

(defproject testclojure "0.1.0-SNAPSHOT"
  :description "FIXME: write description"
  :url "http://example.com/FIXME"
  :license {:name "Eclipse Public License"
            :url "http://www.eclipse.org/legal/epl-v10.html"}
  :dependencies [[org.clojure/clojure "1.6.0"]
                 [org.clojure/core.typed "0.2.84"]
                 [alembic "0.3.2"]]
  :main ^:skip-aot testclojure.core
  :target-path "target/%s"
  :profiles {:uberjar {:aot :all}})

編碼：

(ns testclojure.core
  (:gen-class)
  (:require [clojure.core.typed :refer [ann AnyInteger check-ns]])
  (:import [clojure.lang ISeq]))

(ann ^:no-check clojure.core/mod [AnyInteger AnyInteger -> AnyInteger])

(ann div-by [AnyInteger AnyInteger -> Boolean])
(defn div-by [x y]
  (== (mod y x) 0))

(ann div-by-3-or-5 [AnyInteger -> Boolean])
(defn div-by-3-or-5 [x]
  (or (div-by 3 x) (div-by 5 x)))

(ann euler1 [AnyInteger -> AnyInteger])
(defn euler1 [n]
  (reduce + (filter div-by-3-or-5 (range n))))

(ann -main [-> nil] )
(defn -main []
  (prn (euler1 "a")))

lein compile完全沒有錯誤。

正如check-ns的文檔字符串所述：

不要在已檢查的名稱空間中使用check-ns。 它打算在REPL或單元測試中使用。 建議的clojure.test成語：（是（check-ns'your.ns））

如果將其放在test/testclojure/core_test.clj ：

(ns testclojure.core-test
  (:require [clojure.test :refer :all]
            [clojure.core.typed :refer [check-ns]]
            testclojure.core))

(deftest core-typed
  (is (check-ns 'testclojure.core)))

lein test會正確地抱怨類型問題：
