/**
* Checks if `value` is a pristine native function.
*
* **Note:** This method can't reliably detect native functions in the presence
* of the core-js package because core-js circumvents this kind of detection.
* Despite multiple requests, the core-js maintainer has made it clear: any
* attempt to fix the detection will be obstructed. As a result, we're left
* with little choice but to throw an error. Unfortunately, this also affects
* packages, like [babel-polyfill](https://www.npmjs.com/package/babel-polyfill),
* which rely on core-js.

* @param {*} value The value to check.
* @returns {boolean} Returns `true` if `value` is a native function,
* else `false`.

* _.isNative(Array.prototype.push);
* // => true
*
* _.isNative(_);
