From CommonJS to ES!?

How do I convert
```
const collapse = require('bundle-collapser/plugin');
```
to
```
import collapse from 'bundle-collapser/plugin';
```
I've tried this (along a trillion other wild guesses)
```
import { plugin as collapse } from 'bundle-collapser';

import * as collapse from 'bundle-collapser';

import * as collapse from 'bundle-collapser/plugin';

import { plugin as collapse } from 'bundle-collapser/plugin';
```

But Gulp keeps crashing …
