Yeah, I'd be careful about the license.  I don't see one.
You might contact one of these folks:
https://svn.greenpeace.org/projects/custard/browser/doc/copyright.html

But it looks like something like this would do:

x = { 'value':1, 'children': [
  { 'value': 2, 'children': []},
  {'value' : 3, 'children': [
     { 'value':4, 'children':[] }
     ]}
  ]}
----
{% recurse through children as node starting with x %}
...do something with node.
{% endrecurse %}

No, not everyone needs this.

If you do, consider using Jinja with Django.  The HttpResponse just
wants a string which Jinja is (of course) capable of creating.

As a programmer, I agree.  But the Django templating language is not
only for me, nor am I limited to the Django templating language.
