Is there any way to negate a queryset? Let's supose i have this queryset:

User.objects.filter(first_name='vinicius')

and I want to have the queryset with the objects that is not in first
queryset. I know I can do this:

User.objects.exclude(first_name='vinicius')

But we have cases where we don't know what is the queryset, we only knows
that we want to get the elements that isn't in it, like this:

queryset.negate()

It's good to keep the chainable property of querysets.
