Comment:

 Hi. I'm not sure this is the right place (as yet) for this query.

 It seems like a usage question, rather than a specific bug reports, so I'd
 point you to TicketClosingReasons/UseSupportChannels.

 **Maybe** there's an issue there... if there's a concrete behaviour that's
 wrong but I can't see that from the report.

 > I see the django.db.models.base.Comment.__init__ caches the results.

 `QuerySet` has an internal results cache. `Model.__init__()` creates the
 instance in memory yes, but `ModelIterable` (which is what `.iterator()`
 gives you) instantiates the objects when you iterate it, so that's
 expected behaviour, independent of Jinja vs the DTL.

 If you can narrow this down to something specific that Django is doing
 wrong, we're very happy to have a look.
