2D array in java script docs

Hey everyone, I've heard in 3.2 js now supports 2dimensional arrays. which is most excellent. is there any docs on this? I haven't been able to find anything that doesn't mention that "this work flow will be obsolete once 3.2 is released" however i haven't been able to find info as to the correct way to create one. (unless I'm overlooking something completely obvious) in which case, this will be an easy answer ;)

Thanks in advance!

You just use it the same way as c#does:

var test = new int[5,5];
var test2 : int[,]; // for declaring without assigning

test[1,1] = 5;
Debug.Log(test[1,1]);
