// u64 currently allows negative numbers, and i64 allows numbers greater than `1<<63`.  This is a
// little counterintuitive, but since the discriminant can store all the bits, and extracting it
// with a cast requires specifying the signedness, there is no loss of information in those cases.
// This also applies to isize and usize on 64-bit targets.
