Reporting Obsolete script functions

I tried this experiment... and here's what I got.

I created the following code:

function root(){
    Log.Message(root.caller);
}

function oneUp(){
    Log.Message(oneUp.caller);
    root();
}

function twoUp(){
    Log.Message(twoUp.caller);
    oneUp();
}

function top(){
    Log.Message(top.caller);
    twoUp();
}

I then ran the top function.  My test log, on completion, looks like this.

If you replace <function>.caller with <function>.caller.name you get just the name of the calling function.
