aht / listagent.py
Created December 16, 2009 20:30
"""
A listagent is a factory to conveniently instanstiating sliceagents.
A sliceagent can access and mutate an original list "live": it never
creates any copy of the original and only refers to it via "address
translation" -- normalizing its indices by the size of the original list on
every operation.
>>> x = [22, 7, 2, -5, 8, 4]
>>> listagent(x)[1:].sort()
