in reply to Vendor's support of Perl
Rudy Lippan and I (MySQL employee) are the maintainers, and we are actively trying to make sure DBD::mysql is feature rich, having just added prepared statement support, as well as MySQL Embedded server support. Within days, a version supporting multiple result sets will be coming out.
If something doesn't work in DBD::mysql, we need users to go to MySQL's bug site and enter a bug describing what's not working! ;) That's the only way I know if something is broken, since I physically don't have time to read every forum out there. I do look at the mailing lists on a regular basis, and do my best to address user concerns.
Since you've brought it up here, the bit type will be fixed as well, and maybe even make it into the next dev release (which after some time become part of the stable release)
As well as update the documentation that you refered to.
BTW - what version of DBD::mysql are you running?
