Use goog.object/get/set instead of aget/aset

This is a bug report (with instructions to reproduce) or other issue with the code
(if this is a question or feature request, please do not open an issue and post on the mailing list instead).

ClojureScript now warns on the use of aget/aset with non-integer indexes. I think this code should move to using goog.object/get and set instead?

           (defn declare-class-schema! [klass schema] 
        
             (aset klass "schema$utils$schema" schema)) 
        
           (defn class-schema [klass] 
        
             (aget klass "schema$utils$schema")))

Sounds right to me, thanks for the report! (PR welcome!)

Let me know if this is / starts being actively annoying and I can cut a release. Thanks again for the report.
