I recommend you go back to shoving thing in the Class::DBI hash.  It's a
lot easier and you are writing something for a specific version of
Class::DBI on your own system.  Of course if you were planning to make
this into a CPAN module, you should think twice about doing it this way,
since other people will have different versions.

This is the opposite of the complaint that most people have with Perl --
that DESTROY is never called.

Maybe cdid is not really a unique key of your class, so one CD's DESTROY
cleans up another one?  Maybe you have a scoping problem with %
card_writer_of.  I'm pretty confident that DESTROY is not being called
on objects that are still in scope.
