Can't save a document with an attribute named "ttl"

[mathcoll]

Hello,

I can't get an attribute "ttl" to be saved on a document in a collection. I'm not talking about the ttl attribute of the collection. using lokijs v1.5.12

Here is a sample code for illustration :

var my_ttl = "1234";
var doc = {
    ttl: (my_ttl).toString(),
    another_ttl_string: (my_ttl).toString(),
    another_ttl_integer: parseInt(my_ttl, 10),
};
var db = new loki("my_db.json", {autoload: true, autosave: true});
var coll = db.getCollection("documents");
coll.insert(doc);

And the result in Loki Db file is :

"data":[{
    "$loki":1,
    "ttl":null, // Hum ... what wrong here ??
    "another_ttl_string":"1234", // So a string ; make sense
    "another_ttl_integer":1234, // So an integer ; perfect
}]

So as you can see, I'm just expecting the ttl to be save in Loki document, is there any constraint on naming this attribute ?

Thanks
