"""
A dict subclass for Python 2 that behaves like Python 3's dict

Example use:

>>> from 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 iterators on Python 2.x
(with set-like behaviour on Python 2.7).

>>> for d in (d1, d2):
...     assert not isinstance(d.keys(), list)
...     assert not isinstance(d.values(), list)
...     assert not isinstance(d.items(), list)
