Cannot set! dynamic vars in --watch mode #133
Description
There seems to be an issue to do with how --watch mode establishes dynamic bindings that prevents set! being used on dynamic variables.
Given the project.clj from the README:
(defproject my-proj "0.1.0"
:dependencies [[org.clojure/clojure "1.10.1"]]
:profiles {:kaocha {:dependencies [[lambdaisland/kaocha "0.0-581"]]}}
:aliases {"kaocha" ["with-profile" "+kaocha" "run" "-m" "kaocha.runner"]}
:repl-options {:init-ns my-proj.core})And the following test suite:
(ns my-proj.core-test
(:require [clojure.test :refer :all]))
(deftest a-test
(is (do (set! *warn-on-reflection* true)
true)))Watch and non-watch mode behave differently:
Ambroses-MBP my-proj$ lein kaocha
[(.)]
1 tests, 1 assertions, 0 failures.
Ambroses-MBP my-proj$ lein kaocha --watch
[(E)]
