Summary: extra arg 'name' for __get|set|del__

Initial Comment:
Hello. I am writing an object oriented database 
library for Python I call ObjFS. While rewriting it 
for Python 2.2, I found that the special methods 
__get__, __set__ & __del__ would definately benefit 
from having the attribute's name as an extra argument:

def __get__(self, container, name, oftype=None):
def __set__(self, container, name, value):
def __del__(self, container, name):

In my case, I am using those attribute names to build 
database keys (a tuple of attribute names ordered 
from top most container to the current attribute's 
name) to distribute database content on a shelve 
database. 

Without the extra argument, I must hack my own 
solution using __getattribute__, __setattr__ & 
__delattr__ (which still achieves 12000 writes/second 
on my PIII-800). I wouldn't want Python to change on 
my accord, but I was wondering what the reason was 
for excluding the argument's name in __get__, __set__ 
& __del__. The reason I mention this is if it is 
useful to me, I'm certain it might be useful to many 
other people.

Passing the name would be redundant for the typical use,
where each attribute is described by a separate descriptor.
I guess you're using it slightly wrong, attempting to use a
single descriptor to describe multiple attributes.

(BTW, who are you?  Please log in!  Also, better come up
with a more imaginative name than ObjFS. :-)
