good idea, will add that to the docs (along with another fix from the

umm.. no I have yet to consider the best way to deal with it, I kind of 
assumed people just wouldn't do that ;)

I am planning to start using method attributes so that you could specify 
methods to be inherited (for example if they aren't generated by cdbi and 
so otherwise wouldn't be inherited), or should over-ride or not over-ride 
inherited methods or should be over-ridable or not.

can you mail me (offlist) some examples of what you tried so can I play 
around with them and maybe see a way to fix it nicely.
