class attrdict

[Hallvard B Furuseth]

Does this class need anything more?
Is there any risk of a lookup loop?
Seems to work...

class attrdict(dict):
    """Dict where d['foo'] also can be accessed as d.foo"""
    def __init__(self, *args, **kwargs):
        self.__dict__ = self
        dict.__init__(self, *args, **kwargs)
    def __repr__(self):
        return dict.__repr__(self).join(("attrdict(", ")"))

>>> a = attrdict([(1,2)], a=3, b=4)
>>> a
attrdict({'a': 3, 1: 2, 'b': 4})
>>> a = attrdict([(1,2)], b=3, c=4)
>>> a
attrdict({1: 2, 'c': 4, 'b': 3})
>>> a.b
3
>>> a.d = 5
>>> a['d']
5
>>> a.e
Traceback (most recent call last):
  File "<stdin>", line 1, in ?

>>> a.c

2
>>> del a.c
>>>
