Isn't get_pub_date_list() really just a specialist type of values() call?
foo.objects -> set of all objects
foo.objects.values() -> dictionary containing values from set of all objects
foo.objects.pub_date_values() -> list containing all available dates
and more generally,
foo.objects.ATTR_values() -> set containing all available ATTRs
To maintain the full feature list of get_pub_date_list(), allow:
foo.objects.pub_date_values('year') -> set of all available years
as a special case for datetime fields.
