A marker trait signaling that a
ConfigReaderaccepts missing (undefined) values.The standard behavior of
ConfigReaders that expect required keys in config objects is to return aKeyNotFoundfailure when one or more of them are missing. Mixing in this trait into the key'sConfigReadersignals that if a value is missing for the key, theConfigReadercan be called with a cursor in the "undefined" state.
