I’m not sure what the best way to handle this is, but I think it would be nice if we could have a more explicit “this function takes an optional argument that defaults to some value.

If you don’t provide it, use this default value instead.” syntax in Rust.

I know there are other languages with similar features (e.g., Python), so maybe something like this has already been discussed
