After Angular.js $http request, call complete function regardless of success or failure of promise

Question

How can I ensure that the complete() function will run regardless of the outcome of the $http call using the promise API provided with Angular.js?

$

I'm not the world's greatest expert in Angular.js but understand you can do as follows :

whatever.then(function() {
    // success code here
}, function() {
    // error code here
    return true; // return anything that's not undefined (and not a `throw()`) to force the chain down the success path at the following then().
}).then(function() {
    // "complete" code here
});

You are essentially forced to contrive something from one or more .then(), which is a $q promise's only method.
