Summary: Bug assigning list comprehension to __slots__ in python 2.5
Initial Comment:
I use the package 2.5-4.1mdv2007.1.i586 in mandriva.
I don't know if this has already been reported elsewhere but the following code:
a= ['C','D']
class A(object):
__slots__ = a + ['__'+name for name in a]
def __init(self, c, d):
self.__C = c
self.__D = d
C = property(lambda self: self.__C)
D = property(lambda self: self.__D)
a = A()
results is an a.name attribute with value 'D'.
But using :
b= tuple('C','D')
class B(object):
__slots__ = b + tuple('__'+name for name in b)
def __init(self, c, d):
self.__C = c
self.__D = d
C = property(lambda self: self.__C)
D = property(lambda self: self.__D)
b = B()
b appropriately do not have a b.name attribute.

Sorry, I can't follow you. Why should b have a "name" attribute?
Also, is it intentional that your __init is not named __init__?
