I would like to propose a minor enhancement to a
[https://docs.djangoproject.com/en/1.8/ref/templates/builtins/#for
paragraph] which gives an example on using the "for" tag with
dictionaries:
{{{#!django
{% for key, value in data.items %}
{{ key }}: {{ value }}
{% endfor %}
}}}
Currently it doesn't recall the reader that the lookup order would cause
different output if the "dict" dictionary contains the "items" key than
when it doesn't.
On the other hand a paragraph about defaultdict on
[https://docs.djangoproject.com/en/1.8/ref/templates/language/#variables
another page] suggests using dict instead of defaultdict. But while it
solves the problem of creating an entry by making a lookup it doesn't
solve the problem of "items" key within a dictionary.
I thought that maybe one or both pages could contain a reminder that the
view author should remember not to pass a dictionary with the "items" key
if the template author wants to use that "for key, value" construct.
