/// SPAIK uses the convention:

/// ```
/// for marking variables that become invalidated, and may have pointers that no
/// longer point to valid data. Do not access any variable after invalid!(...)
/// has marked them, even if rustc will let you!
///
/// **Do not rely on all invalidated variables being documented**
