I just got word that improved error handling - the stuff I blogged about previously - is in fact being adressed by the MySQL development team. Very glad to head about that.
(We should not expect it sooner than 5.2 though. This is of course totally reasonable as the 5.1 version has been in beta for some time now. In fact, I gueass it won't take too long before that one will become generally available)
