Should nearest() with accessor return the original object?

If you have colors in the form:

```js
[
  { name: 'myname', hex: '#f0f0f0' },
  ...
]
```

and call:

```js
nearest(colors, differenceEuclidean(), item => item.hex)(somecolor, 1)
```

would you expect to get the _hex_ back (as it is now), or the entire object?
