// FIXME(danielhenrymantilla): #42788
//
// - This creates a (mut) reference to a slice of
// _uninitialized integers_.
// _uninitialized_ integers, which is **undefined behavior**
//
// - This having defined behavior is **unstable**:
// it could become UB in the future,
// at which point it would have be changed.
// - Only the standard library gets to soundly "ignore" this,
// based on its privileged knowledge of unstable rustc
// internals;
