Comment (by Ian Foote):

 While working on #470, I've created a proof of concept implementation that
 allows annotating lookups without requiring a {{{Q}}} object. (See
 
https://github.com/django/django/commit/d67c858198903839b6b5bf15e04cbf7a7072190e.)

 Instead of {{{Model.objects.annotate(boolfield=Q(field__gte=4))}}}, we
 would instead write something like
 {{{Model.objects.annotate(boolfield=F('field') >= 4)}}}.

 This is more flexible than the original proposal here because it allows
 comparing expressions other than fields. For example:
 {{{Model.objects.annotate(boolfield=Random() > 0.5)}}}.

 If this proposed API is accepted, I'll assign this ticket to myself again
 and polish up my proof of concept.

Comment (by Ian-Foote):

 I took a quick look at this and ran into circular import problems when
 setting {{{output_field=BooleanField()}}} or importing {{{Expression}}}
 (both from {{{django.db.models}}}).
