Summary: No attributes in nested functions

Initial Comment:
Python 2.2.1

I need this feature to keep a singleton inside and
local to a particular class method, for example.

This works fine:

>>> def a() :
...   pass
... 
>>> a.abc=23
>>> print a
<function a at 0x141500>
>>> print a.abc
23
>>>

This DOESN'T WORK:

>>> class a :  
...   def perico(self) :
...     pass
... 
>>> b=a()
>>> b.perico.abc=23
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AttributeError: 'instance method' object has no
attribute 'abc'

Not a bug. You're not allowed to set attributes on (bound or
unbound) methods, only on functions.

You can do this by writing a.__dict__['perico'].abc = 23.
