I agree with the reasoning about why the discussion should be moved to
mailing list. This ticket ranks high up in google search for this issue
and it'll be a '''big''' help for many newbies to simply find a workaround
without opening security holes etc.. My '''polite''' request to core
developers is to simply comment on usability/security of this solution.
Most of us are pretty happy with Django templating language and wouldn't
want to switch to Jinja2. However, often there are instances where a
variable lookup is needed as witnessed by the activity on Stackoverflow.
