Firebase set() callback only shows sync errors, but not security rule errors?

Question

In reference to the Firebase set() function, is there a way to detect if the set() failed due to security rule errors?

Sample code (receives null, indicating success, even if the set actually failed due to security rules):

locationRef.set('someValue', function(error) {
    console.log(error);
});

The Firebase docs say that the callback only receives an error if synchronization has failed, but it would be useful get passed an error for security rules too. This way I can confidently tell a user that their data has been saved.

Is there any way to do this? I suppose it would useful for any read/write function with an onComplete callback.

In the case of a security error, the error object will contain a PERMISSION_DENIED code: http://jsfiddle.net/katowulf/ZG9CY/

For instance, if I run the following against a protected path:

new Firebase(URL).set({ hello: 'world' }, function(error) {
    $('pre').text( 'done: '+ JSON.stringify(error) ); 
});

I get the following:

done: {"code":"PERMISSION_DENIED"}

There is a doc somewhere talking about the error codes, when I find it I'll add it to this post. (nope, it's about authentication errors)
