To expand on the others, unlike in TS/JS, Python etc you can cast to the `Any`-trait but cannot use it as if it is any value, you need to convert it to the type you want and then handle the errors. A function that accepts `&str` will never accept a `Any` value, unlike in TS where you can override the type checker using `as`. Worth noting that TypeScript's type system is unsound [0] too.
