Attempts in cljs to #p js/Symbols or objects containing them crash running app

Hi, love hashp and the work you've put into it.

I don't know if my issue ought to be strictly dealt with within hashp-land or within zprint, or if there's some user-config/error possible here. But, either way, attempts to #p (js/Symbol "foo"), or, for example, #p a ReactElement ( which is a JS obj with a Symbol value ), crash the running application, apparently once it gets to zprint:

TypeError: Cannot convert a Symbol value to a string
    at Array.join (<anonymous>)

I could just check if something is Symbol, and elect to not place a #p on that path, but wanted to know if you had any ideas, smells, suggestions or configuration tips?
