StringJoiner in b88

[Joe Bowbeer]

Previously, when StringJoiner was a stream destination, I could collect
into one using the three-arg variant:

  s.into(new StringJoiner(delimiter, prefix, suffix));

For example:

  elements.into(new StringJoiner(", ", "[", "]"));

But I can't now because Collectors.toStringJoiner(delimiter) is the only
option.

What's the recommended workaround?

Should Collectors.toStringJoiner(delimiter, prefix, suffix) be added?
