Policy class defining that hard undefined behaviour should occur on incorrect narrow and wide value, error or exception observation.

Inherits publicly from `base` , and simply defines its wide value, error and exception observer policies to call their corresponding narrow editions.

Included by `<basic_result.hpp>`, and so is always available when `basic_result` is available.

Requires: Nothing.
