[Feature Request] Convert array into single fragment

[Joseph]

Hello, thank for this wonderful library.
I was wondering if you can add a utility which can convert array into single fragment, so you can ignore key prop.
I've implemented by myself.

import React, { Fragment } from 'react';
export default arr => React.createElement(Fragment, null, ...arr);

Don't know if it is useful enough to add to your library.

Just wondering why would someone want to avoid key prop? Are there any benefits of using Fragment over array with key?
