That isn't a troll; Class::DBI's refusal to override things in subclasses
is IMO a complete pain, and something that's shot me in the foot many a
time. Admittedly, DBIC's implementation lets you shoot you in the head if you
want to, but at least it does what it's told :)

Kinda cute, although I worry you're not undef'ing the methods in the package
you think you are - if it's superclass methods it's worrying about overriding
then surely that won't clear them. Are you adding methods to the class you
think you're adding them to?
