 * Therefore for numeric values of `elt`, the only instance in which `not elt` will evaluate to `True` is when `elt` is `0`: `not elt` is `not 0` is `not False` is `True`.
 * All non-zero numeric values of `elt` will evaluate to `False`, e.g., when `elt` is `1`: `not elt` is `not 1` is `not True` is `False`.
