Allow dictionary/hashset-like sections

[Krakean]

For example:

[Server]
Name = 192.168.0.1
[Server.Alpha]
Name = 192.168.0.2
IsAlpha = true
[Server.Beta]
Name = 192.168.0.3
IsBeta = true

If describe it as json, it would look something like this:

{
   "Server" : [
        {
             "Name" : "192.168.0.1",
             "Alpha": {
                    "Name" : "192.168.0.2",
                     "IsAlpha" : true
             },
             "Beta": {
                 "Name" : "192.168.0.3",
                "IsBeta" : "true",
             }
       }
   ]
}

Are they not allowed right now? I'm quite sure you can create ini files like that.
What do you want config parser to do? Transform it into an object or a raw JSON string?
Please clarify your request.
