Comment (by Simon Charette):
For those interested in this feature I'd really appreciate feedback on
comment:23.
An alternative could be to allow `values` and `values_list` chaining so
the following would work
{{{#!python
Author.objects.values_list(Age("dob"),
flat=True).update(dob=timezone.now(), returning=True)
>>> [(35,)]
Author.objects.values().update(dob=timezone.now(), returning=["dob"])
>>> [{"dob": date(...)}] # returning: list has precedence over values()
mask
Author.objects.update(dob=timezone.now())
>>> [Author(id=123)] # Author instances with no fields deferred
Author.objects.update(dob=timezone.now(), returning=["dob"])
>>> [Author(id=123)] # Author instances with all fields but dob deferred
