   The constructor uses the `isValid` class method to test its input argument.
   Valid values are stored in the new instance, invalid values cause an `InvalidArgumentException` to be thrown.
   Other instances of the same class are always considered valid (*re-wrapping*).

   Same as the default constructor,
