cljs.reader/read-string and regular expression

Question

Is this a bug or by design? It seems like CLJS reader cannot read regular expressions:

(cljs.reader/read-string (pr-str #"a"))

error {:message "EOF while reading.", :data {:type :reader-exception, :ex-kind :eof}}

Clojurescript v1.9.908

UPDATE: It works with v1.9.229 and Clojure 1.8.0. I'll try to see which version broke that...

cljs.reader/read-string only reads data in edn format & clojure regular expression #"..." syntax is not part of edn specification. (see http://edn-format.org)

https://cljs.github.io/api/cljs.reader/read-string

Reads one object from the string s. Returns nil when s is nil or empty.

Reads data in the edn format (subset of Clojure data): http://edn-format.org

opts is a map as per cljs.tools.reader.edn/read
