 I used to have context processor that returned a dict of all registered
 model classes. This used to work in Django 1.2.x very well and removed the
 need of redundant imports.

 Let's refer to [https://docs.djangoproject.com/en/1.3/ref/templates/api/
 documentation]:

 > If any part of the variable is callable, the template system will try
 calling it.

 And the change:

 > Changed in Django 1.3: Previously, only variables that originated with
 an attribute lookup would be called by the template system. This change
 was made for consistency across lookup types.
 This is a pretty big design change, I wonder what "consistency" implies
 here. For example, you can not do anymore in the templates:
 {{{
     {{ User.objects.all }}
 }}}
 Because your User will become and User instance, since it's looked up in
 Context, which is an dictionary. As a side effect, there is no way you can
 use class in the template anymore.
