An empty class 'Object' in builtins, which can be instantiated (with optional inline arguments as attributes (like dict)), and attributes added. Convenience - Easy OO variable container - known to pickle etc.

idea:

class X(object):
    def __init__(self,_d={},**kwargs):
        kwargs.update(_d)
        self.__dict__=kwargs
class Y(X):
    def __repr__(self):
        return '<Y:%s>'%self.__dict__

------

x=X(spam=1) 
x.a=3

This has been requested in various forms over the years. See the "bunch" discussion on the python-dev mailing list from over a year ago. There may have even been a PEP. I believe the general consensus was "it would be convenient sometimes, but it is *trivial* to implement it as necessary". Also, not every X-line function or class should be included with Python.

[avassalotti]

This has almost no-chance to get included in the standard library. Also,
Python 2.6 will include namedtuple (see
http://docs.python.org/dev/library/collections.html#collections.namedtuple),
which provides similar functionally.

Closing this issue as rejected.
