Feature Request: transform object property assignment to `defineProperty` 

refactor
```
myObject.someProp = 'someValue'
```
to
```
Object.defineProperty(myObject, 'someProp', {
  value: 'someValue'
})
```

I use this technique a lot for bypassing TypeScript :grin: But I believe we may be able to find good use cases for it as well. : )
