is it possible to get all the  super columns of a  supercolumn family with lazyboy?

>>> from lazyboy import *
>>> from lazyboy.key import Key
>>> connection.add_pool('Keyspace1', ['localhost:9160'])
>>> x=Record()
>>> x.load(Key('Keyspace1','Supern1', 'user_id'))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/mark/work/common/lazyboy/record.py", line 140, in load
    dict([(obj.column.name, obj.column) for obj in _slice]))
