This somehow is a follow-up to issue #18, in my case real issues occur due to the browser changing the order of the object elements.

The following code shows the problem in my current version of Chrome (59.0.3071.115) as well as in Firefox (53.0.3):
JSOG.parse('{"a": {"@ref": 0}, "11": {"@id": 0}, "3": {"@ref": 0}, "2": {"@ref": 0}}')
This results in:
Object {2: undefined, 3: undefined, 11: Object, a: Object}

Inspecting the issue I found out that objects which use numbers as keys are sorted in the numerical order of the keys, at least when using JSON.parse:
JSON.parse('{"a": {"@ref": 0}, "11": {"@id": 0}, "3": {"@ref": 0}, "2": {"@ref": 0}}')
Will result in:
Object {2: Object, 3: Object, 11: Object, a: Object}

Am I using JSOG in any wrong way or is this really an issue?
