Value properties are also detected specifically:

```js
Object.defineProperty(exports, 'a', {
value: 'no problem'
});
```

To avoid matching getters that have side effects, any getter for an export name that does not support the forms above will
opt-out of the getter matching:

```js
// DETECTS: NO EXPORTS
Object.defineProperty(exports, 'a', {
value: 'no problem'
get () {
return 'nope';
