How to use the react-hot-loader.foo function in react-hot-loader

import { hot as namedHot2 } from 'react-hot-loader'
import { hot as notRHLHot } from 'not-react-hot-loader'
import * as RHL from 'react-hot-loader'
import * as RHL2 from 'react-hot-loader'
import * as NOTRHL from 'not-react-hot-loader'

const App = () =&gt; <div>Hello World!</div>

const a = hot(module)(App);
const z = rootHot(App);
const b = namedHot(module)(App);
const c = namedHot2(module)(App);
const d = RHL.hot(module)(App);
const e = RHL2.hot(module)(App);

foo(module)(App);
notRHLHot(module)(App);
namedFoo(module)(App);
RHL.foo(module)(App);
NOTRHL.hot(module)(App);

// should not drop incomplete reference
namedFoo(module);

export { a, b, c, d, e, z };
