I noticed a slight (but annoying) difference between slicing an
EmptyQuerySet and slicing a standard QuerySet. It seems like slicing an
EmptyQuerySet should return an EmptyQuerySet, rather than returning a
list.
Example:
{{{
>> from django.contrib.auth.models import User
>>
>> type(User.objects.all())
<class 'django.db.models.query.QuerySet'>
>> type(User.objects.all()[:0])
<class 'django.db.models.query.QuerySet'>
>> type(User.objects.all()[:10])
<class 'django.db.models.query.QuerySet'>
>>
>> type(User.objects.none())
<class 'django.db.models.query.EmptyQuerySet'>
>> type(User.objects.none()[:0])
<type 'list'>
>> type(User.objects.none()[:10])
<type 'list'>
}}}
