Your example doesn't help your argument here, as square should be taking `T` instead of `Option<T>`, a good use case for `Option::map`.

But if you are speaking about ergonomics of handling Options, it is being improved upon with the usage of try operators with Options as well as possibly seeing try expressions in the near future.

I don't think lack of ergonomics is a good justification for usage of unwrap, but that is entirely subjective. However, I do see the misappropriation of `unwrap` as a signal that the ergonomics in Rust are lacking and it's something that needs to be addressed, so again I do sympathize.
