Notes
=====
This allows you to set up a breakpoint anywhere in your template code,
by simply writing {% pdb_debug %}.

You can then access your context variables using context.get(..) at the pdb
prompt. Optionally, install the ipdb package for colors, completion, and more (easy_install ipdb).

def object_list(request, queryset, extra_context=None, template_name='', paginate_by=None):

    """list_detail.object_list replacement. 

    This allows you to avoid having to refactor any of your function-based 
    views that used object_list into class-based views because of the 
    deprecation of object_list in >= django 1.5. If you must.
