"""
A dict subclass for Python 3 that behaves like Python 2's dict
Example use:
>>> from past.builtins import dict
>>> d1 = dict() # instead of {} for an empty dict
>>> d2 = dict(key1='value1', key2='value2')
The keys, values and items methods now return lists on Python 3.x and there are
methods for iterkeys, itervalues, iteritems, and viewkeys etc.
>>> for d in (d1, d2):
... assert isinstance(d.keys(), list)
... assert isinstance(d.values(), list)
... assert isinstance(d.items(), list)
