+1 for appending `?` to boolean values as well as functions that return a boolean.

I see this too: ``` user> (require '[cats.monad.either :as either]) nil user> (either/left "foo") IllegalArgumentException Multiple methods in multimethod 'simple-dispatch' match dispatch value: class cats.monad.either.Left -> interface clojure.lang.IPersistentMap and interface...

+1

Looking at the history it seems a PR was rejected with this functionality: https://github.com/yuya373/emacs-slack/pull/505 I think it's a useful feature

Not exactly, `(when (f/ok? ...` returns nil on a failure whereas I'd like to return the failure.

Any update on this? IE support would be really handy
