Hi, thanks for the PR. However, I think it makes more sense to use the common way of registering a controller:

angular.module('xmpl').controller('XmplController', function($scope, greeter, user){
  $scope.greeting = greeter.greet(user.name);
});

Can you update the PR?

Updated PR, I actually kept in the original run block. Although i think it doesn't add much more clarity if i look back at what this part of the docs is explaining

     angular.module('xmpl', ['xmpl.service', 'xmpl.directive', 'xmpl.filter']).
        run(function(greeter, user) {
          // This is effectively part of the main method initialization code
          greeter.localize({
            salutation: 'Bonjour'
          });
          user.load('World');
        }).
        controller('XmplController', function($scope, greeter, user){
         $scope.greeting = greeter.greet(user.name);
        });
