Sometimes you want a better `dict` in Python...

HashableDict.py

import __builtin__

class HashableDict(__builtin__.dict):
    '''and with .attr capability'''

    def __init__(self, *av, **kw):
        return __builtin__.dict.__init__(self, *av, **kw)

    @staticmethod
    def dict__hash(d):
        return hash(tuple(sorted([
            (HashableDict.dict__hash(k) if type(k) is dict else k,
             HashableDict.dict__hash(v) if type(v) is dict else v)
            for k, v in d.items()])))

    def __hash__(self):
        return self.dict__hash(self)

    def __eq__(self, other):
        return self.__hash__() == self.dict__hash(other)

    def __getattr__(self, attr):
        if attr in self:
            return self.get(attr)
        raise KeyError, attr
