Nice! Thanks for this gist.

I am having the following error:
django.template.base.VariableDoesNotExist: Failed lookup for key [request] in u"[{'False': False, 'None': None, 'True': True}, {u'STATIC_URL': '/static/'}]"

I think it is happening because compress is trying to access request when compressing. Is there any way to avoid this? Did you get this error in the past?
