Yes, implementation of the value level can stay, but assertion like as X is a type level. Currently implementation cannot compile because of lack of proper typing, there is a way to solve it without any assertion that is why I left it as it is, so with compile error.
You can modify the implementation, the key is to have it working as original + typed safe.

We're a place where coders share, stay up-to-date and grow their careers.
Now the interface of the function works in reverse way, what is correct is incorrect 😉
If i understood it correct, we are not allowed to change implementation of the method, just introduce types to make it work, right ?
