Hi,
I understand why contextlib.nested is deprecated.
But if I write a program for an old python version w/o the multiple form
of with, I have (nearly) no other choice.
In order to avoid the following construct to fail:
with nested(open("f1"), open("f2")) as (f1, f

If been watching this thread for a while, and I think that your problems
will go away if you write actual nested with-blocks:
with Foo("a") as a:
with Foo("b") as b:
print a.tag

Hello!
I have been running in to some problems when using
contextlib.nested(). My problem arises when using code similar to
this:
from __future__ import with_statement
from contextlib import nested
