`User.objects.get(4)` should give a good error message

[boxed]

The current error in django is:

TypeError: cannot unpack non-iterable int object

If you do User.objects.get('123') you get:

ValueError: too many values to unpack (expected 2)

What error message should be shown?

Maybe something like:

"Got 4, but get/filter takes keyword arguments or Q objects. Maybe you meant pk=4?"

[boxed]

I think the check that should be made is that none of the *args should be non-Q-objects.
