Comment:
I've written a basic patch enabling this, against the current trunk:
http://github.com/miracle2k/django/tree/10972-aggrating-expr
There are some things I had trouble with, where I'm definitely not sure
what the right thing do to is, for example the way the Where node now
needs to handle children who's as_sql() returns a 2-tuple (sql, params):

Generally though, it seems to work. Maybe this can inspire someone to do a
better implementation. A set of simple tests included.
