Nope. It'll just ignore the subclass that's been incorrectly setup.
I think it's safer that way.

You'd set up that hierarchy yourself as
WebDBI::db -> MyDBI::db -> DBI::db
and then tell the DBI that you want to use WebDBI as the 'root
class' (umm, perhaps a poor name).

I'm not sure what you mean. Can you expand on that? (re subclassing
Apache::DBI)
