caller. Every control path in a diverging function must end with a `panic!()` 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 $\bot$.
