I agree it’s not that of a issue (I was just trying to see it with the eyes of someone not so familiar with the language). But this new way to unwrap an optional in a given context would allow us to do what we want most of the time when doing the if let foo = foo dance, which is access Optional<T> as T when it's safe, while giving the bonus of being able to direct mutating the original variable if desired. It would be an alternative way for when we don't necessarily want to create a new variable to just access a existing one.
