Empty string key not supported

[yunjiangster]

I am using the latest pyhocon and it fails to parse the simplest json dictionary with empty string:

import pyhocon
from pyhocon import ConfigFactory
ConfigFactory.parse_string('{"": ""}')

Traceback (most recent call last): ... assert key_index < len(key_path), (key_index, key_path, self) AssertionError: (0, [], ConfigTree())

On the other hand, json handles it perfectly fine.

import json
json.loads('{"": ""}')

{'': ''}

Thanks for your attention. I am surprised this simple issue hasn't been raised before.

pip show pyhocon
