 We will add expressions support instead. This should allow users to do
 what is wanted in this ticket.

Comment:

 In order to do this, we would need to formalize the interface that Q
 objects expose. I'm not sure we're in a position to do that at the moment.
 Long term, it's certainly a desirable goal, though.

 It would be nice if custom Q-objects could be transparently used in
 `filter()` and `exclude()` calls (if they provide an `__invert__()`
 method).

 The following code illustrates the desired behaviour:
 {{{
 #!python

 class QuerySet(models.query.QuerySet):
 def filter(self, *args, **kwargs):
 if not kwargs and len(args) == 1 and hasattr(args[0],
 'add_to_query'):
 return self.complex_filter(args[0])
 return super(QuerySet, self).filter(*args, **kwargs)

 def exclude(self, *args, **kwargs):
 if not kwargs and len(args) == 1:
 return self.complex_filter(~args[0])
 return super(QuerySet, self).exclude(*args, **kwargs)

 }}}
