Rating my own module here. Bit bi-ass perhaps...
Nevertheless i have used this in almost any project I have build. It serves me super. I should still update the documentation and add those spiffy things as constant-accessors and better support for objects without loosing to much of the easy interface.
It's good, it's fast - what more can we say?
Although it is one of the best developed perl-modules around (IMHO) I think it could use a bit nicer API - the length of the function names makes it error-prone. One solution would be returning (browsable) recordsets instead of a handler. (just daydreaming here)
