It should also be added that since Django 1.3, you've been able to put {% load
url from future %} at the top of your templates, which allows you to cleanly
introduce the use of the new tag into your templates. This was also documented
in the release notes for Django 1.3.
To the original poster -- thanks for the suggestion, but no, this isn't going
to be reverted.
Ironically, your "3 line" example points out exactly why the change has been
made -- it allows you to use a variable to be used as your URL name, whereas
the unquoted behavior requires that your url is a known, static string. Without
the new behavior of the URL tag, you wouldn't be able to use the URL tag with a
value set in a with tag.
