There's a bit of an oddity in Django here, that actually has nothing to do
with autoescape. There are three "built-in" tags (block, extends, and
include) that are only made available as built-ins as a side-effect of
importing the loader module within django.template. So you get the error you
noticed if you try to create a Template that uses one of these tags without
ever importing django.template.loader. But if you import loader, all works
as per the doc you pointed to:
Python 2.7.2 (default, Jun 12 2011, 14:24:46) [MSC v.1500 64 bit (AMD64)] on
win32
Type "help", "copyright", "credits" or "license" for more information.

>>> t = Template(ts)
