Have a read of the rust release notes [0] to see why the ? operator actually improves code readability. It's not obvious from the simple example given the original article, but as the release notes mention it makes things like the following: try!(try!(try!(foo()).bar()).baz()) much more readable: foo()?.bar()?.baz()?
