WARNING: cljs.core/bit-or, all arguments must be numbers

[arichiardi]

I have noticed that we have a spurious warning when doing this at the REPL:

cljs.user=> (int \uD7ff)
            ⬆
WARNING: cljs.core/bit-or, all arguments must be numbers, got [string number] instead. at line 1 
0

It does not happen in vanilla ClojureScript:

$ ./script/repljs 
To quit, type: :cljs/quit
cljs.user=> *clojurescript-version*
"1.9.1008"
cljs.user=> (int \uD7ff)
0

I will try to dig more, any hint is more than welcome!

This happens because the line in target/cljs/tools/reader/edn.js that triggers the warning is compiled as:

cljs.tools.reader.edn.upper_limit = ("\uD7FF" | (0));

Digging digging...
