@Deprecated
    default String join(CharSequence delimiter) {
        return map(Objects::toString).collect(Collectors.joining(delimiter));
    }
Shortcut for calling {@link Stream#collect(Collector)} with a
{@link Collectors#joining(CharSequence)}
collector.

@deprecated - Use {@link #toString(CharSequence)} instead. This method
will be removed in the future as it causes confusion with
{@link #innerJoin(Seq, BiPredicate)}.
