Using `->` or `*` on an `Expected` will assert if the `Expected` hasn’t been
checked for errors, even if it does not contain an error. Something like this
should work, but please verify that this actually compiles.
Furthermore, we normally spell out types instead of using `auto` in cases where
the type isn’t obvious from the context. Moreover, I think there’s value in
being a bit more verbose here since this documentation is mainly intended for
people new to libtooling.
