#### `typeof module.exports` is always 'function'
#### ownKeys is not supported
Because the library is unable to know in advance what type of value will be assigned to `module.export`, it choose the most generic one as ES6 Proxy target.
However, `(function(){}) instanceof Object === true`
Reflect.ownKeys(), Object.keys(), for-in loop, console.log(), ... are not available on the module exports (only).
eg.
```
Object.keys(require('foo.js'));
```
will throw a `TypeError: ownKeys not implemented` exception.
However for-of loop works properly.
