Description

The error message is

No method in multimethod 'check' for dispatch value: :reify

The following is a minimal test case which fails:

core.clj
(ns core-typed-bug.core
  (:require [clojure.core.typed :refer :all]))

(ann-protocol ITypedTest
              get-data [ITypedTest -> Any])
(defprotocol> ITypedTest
  (get-data [this]))

(ann typed-test [String -> ITypedTest])
(defn typed-test [input]
  (reify ITypedTest
    (get-data [_] input)))

(defn> testfn :- Any
  [asdf :- Keyword, in :- ITypedTest]
  (get-data in))
