difference b/w `export default hot(module)(App);` and `export default hot(App);`

In the docs there are two styles:
export default hot(module)(App);
and
export default hot(App);
seems like a big difference and curious as to what it means
It is import {hot} from 'react-hot-loader'
vs import {hot} from 'react-hot-loader/root'
.
The second provides more "magic" out of the box, but works only for webpack
. See the code -- https://github.com/gaearon/react-hot-loader/blob/master/root.js
Basically, it setup HMR for the parent module, not the current module - export default hot(moduleParent)(App);
- so if in the future the current module will fail to load (like a syntax error) - the "parent" will still able to reload it.
thx
