There are two issues I see here:
- `book.toObject()` would have to do deep conversion and you may not want it. Let’s say birthdate is immutable map `{day, month, year}`*. This would convert `birthdate` to `Object` even though you didn’t want that.

- this can handle only String keys. My proposal could be extended so this would work:

```js
   const {[someNonStringKey]: value} = someMap;
```
We already have a syntax for that in es6.

PS: * I know we have `Date()` for that purpose. Just for demonstration.
