Sure, but this model doesn't hold for resource defaults :) >> and thus not inside a class that may include all your other classes? >> (we have a module 'base' that does all the logic for which other >> classes should be included) > > This can be pretty easily done using fully qualified variables, but it's even > better done using extlookup or equivalent.
