16389	In Django 1.3, dictionary lookup now calls the value if callable making classes unusable	Domen Kožar	nobody	"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."	Bug	closed	Template system	1.3	Normal	invalid	template lookup dictionary callable	domen@…	Unreviewed	0	0	0	0	0	0
