* 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. |
