We call such functions "diverging" because they never return a value to the
caller. Every control path in a diverging function must end with a
`fail!()` or a call to another diverging function on every
control path. The `!` annotation does *not* denote a type. Rather, the result
type of a diverging function is a special type called $\bot$ ("bottom") that
unifies with any type. Rust has no syntax for $\bot$.
