I see that this handler uses `ex-str`, which is nice because `ex-str` in
turn calls `*explain-out*` which is user-configurable.
Is there a recommended way to configure `s/*explain-out*` such that this
configuration will be run before other namespaces are loaded?
For instance, this code would set up Expound, but right now I'm not sure
how to reliably run it before other namespaces load:
(require '[expound.alpha :as expound] '[clojure.spec.alpha :as s])
(alter-var-root #'s/*explain-out* (constantly (expound/custom-printer
{:print-specs? false :show-valid-values? true :theme :figwheel-theme})))
Thanks,
Ben
