Most of my queries, where I need to wake up objects, has the form::

     brains = catalog(portal_type='Document')
     objects = []
     for brain in brains:
         try:
             obj = brain.getObject()
             if not obj is None:
                 objects.append(obj)
         except:
             pass

So it will not break any of my code, and I guess that most do something
similar.



Another thing is that I think that this pattern is so common that the
catalog should have a query method where brains are automatically
converted to objects. Like:

     objects = catalog.getObjects(portal_type='Document')

That would be a handy time saver.
