There's no way to enable warn-on-reflection from the command-line when running clojure.main

Question

Per Slack chat:

The {{-Dclojure.compile.warn-on-reflection=true}} property only affects the Compile wrapper. A "regular" property should be added that affects * } when running {{clojure.main}}.

Alex said:

"It might make more sense to leverage the existing compiler-options infrastructure instead for that."

Answer 2

As a temporary workaround:

Putting

(alter-var-root #'*warn-on-reflection* (constantly true))

in user.clj also seems to work.
