Hi all,
I ran into the follow behavior while making sure Django works
correctly on PyPy. The following behavior was observed in all tested
versions of CPython (2.5, 3.1):
def f(**kwargs):
... print(kwargs)
...
kwargs = {1: 3}
dict({}, **kwargs)
{1: 3}
f(**kwargs)

This behavior seems pretty strange to me, indeed PyPy gives the
TypeError for both attempts. I just wanted to confirm that it was in
fact intentional.
Oleg already answered why f(**{1:3}) raises a TypeError. But your
question seems to be rather why dict(**{1:3}) doesn't.

Is it okay to include this in Python 2.7 b2 release? It

Yes, we have different opinions. My personal take is to wait a week before
you email python-dev if there has been no activity. That is enough time for
people interested in the patch to get to it as we all have different
schedules. Any faster and it feels like noise on the list to me.

Hi,
Python contains code specific to OS/2 (eg. see Modules/posixmodule.c). I read
in Wikipedia that IBM has discontinued OS/2 support in 2005. Do we still
support OS/2 or not?
I'm asking because I'm working on a patch modifying OS2 specific code, but I'm
unable to compile nor test my changes.

Yes. Andrew MacIntyre maintains the OS/2 port:

As was recently discussed, what constitutes support varies in perception.
