This already implies that it is an unsafe function (in general, i.e.
modulo klint, or a way to force the user to have to write `unsafe`
somewhere else, or what I call ASHes -- "acknowledged soundness
holes").
If we consider as safe functions that, if used correctly, do not cause
UB, then all functions would be safe.
Cheers,
Miguel
