The previous example showed that the type system forbids any mutations
of owned boxed values while they are being borrowed. In general, the type
system also forbids borrowing a value as mutable if it is already being
borrowed - either as a mutable reference or an immutable one. This restriction
prevents pointers from pointing into freed memory. There is one other
case where the compiler must be very careful to ensure that pointers
remain valid: pointers into the interior of an `enum`.
