Hi,

I've read about some json handling functions in Joe Armstrong's book
(Programming Erlang, 2nd Edition, Page 84): maps:to_json/1,
maps:from_json/1 and maps:safe_from_json/1.

Now, In erlang shell, I see this. No such functions.

> maps:module_info(exports).
[{fold,3},
 {map,2},
 {size,1},
 {without,2},
 {module_info,0},
 {module_info,1},
 {values,1},
 {update,3},
 {remove,2},
 {put,3},
 {new,0},
 {merge,2},
 {keys,1},
 {is_key,2},
 {from_list,1},
 {get,2},
 {find,2},
 {to_list,1}]

Are these json functions planned to be released in final 17.0?

Thanks,

Zsolt
