Facebook Comment Code - What is it?

Question

Recently I've seen some people using a string of code in their comment or wall post in order to do something interesting, such as hyperlinking the whole text. It looks quite fun though, but I don't know whether it's Facebook-defined code or any kind of language behind.

For example: @@+[0:[158038637615605:0: YOUR TEXT HERE ]]

I guess the number 158038637615605 could be an app's ID.

Any idea?

The code seems to be how Facebook is able to encode links in text without having to store any additional meta data. I assume they expect the format to be so strange as to not occur in a persons normal updates. The syntax was probably released by an engineer, or gleamed by someone examining the JavaScript operations as a user goes about tagging something.

A similar thing I've been seeing goes along the lines of:

Your phone has a name. To figure it out, you take the last three digits of your phone number - for example 635 and type it the comment section of this post like @*[635:0] and then remove the * and post, and you get your phone's name.

I suspect they're making exceptions now to prevent the user from typing it manually.

Site note; 158038637615605 seems to be the ID of a Facebook page.
