Hi, all!

What if we have to overload ACCEPT_CONTEXT to do something like this,
but using DBIC::Schema?  What would be the recommended inheritance
chain? Catalyst::Model::DBIC::Schema acts as a glue between the actual
Catalyst model and the Schema classes, so I'm a little confused about
where to start...  In this particular case, we'd like to access $c
from model in order to overload subroutines (trigger-like) to track,
for example, which user modified what...

Thanks in advance,

Juan.
