The JSON form for [Q11](https://github.com/xtdb/xtdb/blob/2.x/modules/datasets/src/main/clojure/xtdb/datasets/tpch/xtql.clj#L195-L212) triggers the following internal server error: ``` 8..KqO.HTTP/1.1 500 Server Error Content-Type: application/json;charset=utf-8 Content-Length: 425 Server: Jetty(11.0.18) {"@type":"xt:error","@value":{"xtdb.error/message":"TODO what should literals in out specs do...

Hi Could you please add [cl-transit ](https://github.com/jsulmont/cl-transit): a CL library for dealing with [transit-format](https://github.com/cognitect/transit-format). Thanks!

cannot encode a dotted pair

Surprisingly JZON fails to encode a dotted pair, as it assumes it will be able to call `length` on the `cdr` ```lisp (jzon:stringify '(1 . 2)) ```

issue with reading JSON floats.

Thanks for that neat lib!! `read-json-number` seems to behave incorrectly: ```lisp (let ((cl:*read-default-float-format* 'double-float)) (shasht:read-json "-3.14159")) ``` returns: ```lisp -3.1415900000000003d0 ``` when ```lisp (let ((cl:*read-default-float-format* 'long-float)) (read-from-string "-3.14159")) ``` returns:...
