    A pickler obtained from this pickler and an alternative pickler. To pickle a value, this pickler is tried first. If it cannot handle the object (as indicated by its `canPickle` test), then the alternative pickler is tried. To unpickle a value, this unpickler is tried first. If it cannot read the input (as indicated by a `UnpickleFailure` result), then the alternative pickler is tried.

    V

      The handled type of the returned pickler.

    U

      The handled type of the alternative pickler.

    that

      The alternative pickler.

    A pickler representing a `~`-pair of values as two consecutive pickled strings, separated by a comma.

    that
