Is this a bug in the conversion of the clojure keyword to theJavaScript
object?
I think there's probably an issue with string conversion in your
program. In ClojureScript keywords are not separate objects. Instead
they are simply strings that start with a bizarre unicode character.
Example from

Hi Shantanu,
#1 is a bug.
#2 is not possible because `import` doesn't exist in ClojureScript: it

Protocols and types should be accessible with normal `require` in
ClojureScript.

I do not disagree. Those elements will be in place by the 1.0.0
