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`
However, `(function(){}) instanceof Object === true`.
As workaround, you can use `instanceof` against the `module.exports`, this will always retuns the expected result.
##### Example:
###### module `./myModule.js`
```
module.invalidable = true;
module.exports = new Date;
```
###### main module `index.js`
```
require('module-invalidate');
var myModule = require('./myModule.js');
console.log(myModule instanceof Date); // true
```
#### Only direct variable access is handled
