spec/with-gen breaks swagger spec

[willspecht]

Library Version(s) "2.0.0-alpha28"

Problem

If you use a spec that is created with with-gen it breaks swagger generation, with error:

10:55:26.898 ERROR [compojure.api.exception] (XNIO-8 task-8) Unable to resolve spec: :clojure.spec.alpha/unknown

Sample c2 code that recreates the issue

(ns c2.spec
  (:require [compojure.api.sweet :refer [context GET POST resource]]
            [ring.util.http-response :refer [ok]]
            [clojure.spec.alpha :as s]
            [spec-tools.spec :as spec]
            [clojure.spec.gen.alpha :as gen]))

(def valid-guid?
  (s/with-gen
    int?
    (constantly 1)))

(s/def ::search-id valid-guid?)

(def routes
  (context "/" []
    :tags ["spec"]
    :coercion :spec

    (POST "/get-guid" []
      :summary "always return 1"
      :return ::search-id
      (ok {:inst (gen/generate (s/gen ::search-id))}))))

This is only an issue with clojure 9, updating to 10 fixes this issue. It seems in 9 s/form gives :clojure.spec.alpha/unknown for any with-gen spec

also to note, you can't use anonymous functions in with-gen or it will break as well.
