        If ``type`` is given (one of str, float, int, datetime, or timedelta)
        or can be inferred from the ``default``, we parse the command line
        arguments based on the given type. If ``multiple`` is True, we accept
        comma-separated values, and the option value is always a list.

        For multi-value integers, we also accept the syntax ``x:y``, which
        turns into ``range(x, y)`` - very useful for long integer ranges.

        ``help`` and ``metavar`` are used to construct the
