WARNING: cljs.core/bit-or

[zalky]

Seeing a warning in cljs:

WARNING: cljs.core/bit-or, all arguments must be numbers, got [clj-nil number] inste
ad. at line 601 /Users/zalan/.boot/cache/tmp/Users/zalan/src/semion/onty/2ao/-bj0ipr
/main.out/automat/fsm.cljc                                                         

Simple test case:

(ns simple.core
  (:require [automat.core :as a]))

(a/compile [1])

Tested with:

• boot: 2.5.5
• clojure: 1.8.0
• cljs: 1.8.40, 1.9.76, 1.9.225

It doesn't seem to have any affect in my simple use cases. Is this a known issue? Is this something to worry about?

I'm also seeing this error, but bit-or isn't used anywhere in the library, so I think it's something else that's causing it.
