The link to your snippet doesn't work for me.
It sounds like a neat idea. However, I've never come across a
situation where I've needed to do that in 2.5 years of developing
Django templates, and, whilst I agree that we don't want to get into a
holy war about whether stuff should be done in templates or views, I
reckon the reason I've avoided this sort of thing is because I must
have done that sort of work in the view :)
