Off-topic: Should we rewrite join!/try_join! with proc-macro to allow passing expressions directly here?

join!(get_book(), get_music())

Another error seems to be that mio has moved to tokio-rs (https://github.com/tokio-rs/mio) and the following link is out of date.

[`mio`]: https://github.com/carllerche/mio

https://travis-ci.com/rust-lang/async-book/builds/122145149#L817


One thing you may have noticed in the first example above is that we
had to call `.fuse()` on the futures returned by the two `async fn`s,
as well as pinning them with `pin_mut`. Both of these calls necessary
