{{{
def in_bulk(self, id_list):
    assert isinstance(id_list, list), ""in_bulk() must be provided with a list of IDs.""
    assert id_list != [], ""in_bulk() cannot be passed an empty ID list.""
    ...
}}}

This means you can't pass in some other iterable that returns ids, which is a bit of a shame. Suggest doing this instead:

{{{
def in_bulk(self, id_list):
    try:
        iter(id_list)
    except TypeError:
        assert False, ""in_bulk() must be provided with a list of IDs.""
    id_list = list(id_list)
    assert id_list != [], ""in_bulk() cannot be passed an empty ID list.""
    ...
