so people using something like systemjs won't break the promise chain and at the same time shows that it's a promise
```es6
Promise.all({
app1: System.import('app1').then(module => module.main()),
app2: System.import('app2').then(module => module.main()),
app3: System.import('app3').then(module => module.main())
})
.then(function(injectors) {
console.log('dem injectors', injectors);
});
```
