[BangPypers] Nice "feature"

[Hussain Bohra]

Atleast on changing list, you gets an exception. 

On updating dictionary living inside tuple wont throw an exception as well.

>>> foo = (1,[2,3,4], {'a':1})
>>> foo[2].update({'b':2})
>>> foo
(1, [2, 3, 4], {'a': 1, 'b': 2})
>>>

Both python 2.6 and 3.1 behaves in the same way.

With Python 2.6.5 (on ubuntu) I get even more bizarre behavior:
>>> foo=(1,[2,3,4])
>>> foo[1]+=6
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not iterable
>>> foo
(1, [8, 9, 10])
