According to documentation user.get should return an array, yet it returns a hash.

Sending: {"jsonrpc": "2.0", "method":"user.get", "params":{}, "auth":"0aaee60cde5bf6ee9d1f15bf944bd11d", "id":1}
Response: {"jsonrpc":"2.0","result":

{"1":"1","2":"2","3":"3"}

,"id":1}

Setting to critical as consistent return types are important. Also looking at the code I am wondering if the resultant hash is due to the user.get function not returning an array or if the function which calls user.get not properly parsing the return as a JSON array.
