A really weird way to inject dependencies with AngularJS

example.js

angular.module('test', []).controller('Test', inject([

  '$scope',
  '$http'
  
], function () {

  'use strict';

  this.$scope.wat = 'hallo';

  this.$http.jsonp('http://reddit.com/.json?jsonp=JSON_CALLBACK').then(function () {
    this.$scope.wat = 'woo reddit';
  }.bind(this));

}));

inject.js

function inject (deps, cb) {
  function getDeps () {
    var args = [].slice.call(arguments);
    var ctx = {};

    angular.forEach(deps, function (dep, i) {
      ctx[dep] = args[i];
    });

    return cb.call(ctx);
  }

  return deps.push(getDeps) && deps;
}
