Subject: [PATCH 3/6] ds: drop set_writer_func support
Date: Mon,  3 Jun 2019 01:52:03 +0000
Message-ID: <20190603015206.7871-4-e@80x24.org> (raw)
In-Reply-To: <20190603015206.7871-1-e@80x24.org>

This is not used by perlbal for OpenSSL support, either;
and it does not appear to be the right layer for doing
write translations anyways (IO::Socket::SSL uses `tie').
