I should have brought this up to python-dev before--sorry for being so
slow. It's already in the tracker for a couple of days:

The idea: PyGetSetDef has this "void *closure" field that acts like a
context pointer. You stick it in the PyGetSetDef, and it
In issue 5920, Mark Dickinson raises an issue having to do with
float.__format__ and how it handles the default format presentation type
(that is, none of 'f', 'g', or 'e') versus how str() works on floats:

Hi,
Encouraged by a conversation with Martin at PyCon 2009
I've prepared a version 1.1b of the turtle module and I'd like to
get some advice or assistance to get it into the beta as explained
below. Thus I'd appreciate very much if also the release manager
would take notice of this posting.

Hi,
Python ships with a profiler module which, unfortunately, is almost useless in
a multi-threaded environment. *
I've created an alternative profiler module which queries per-thread CPU usage
via netlink/taskstats, which limits the applicability to Linux (which shouldn't
be much of an issue,

This doesn't sound right. The functions in the third par

Yep.

This would have to be considered in conjunction with the

In Python 2, PyMapping_Check will return 0 for list objects. In Python
3, it returns 1. Obviously, this makes it rather difficult to
differentiate between mappings and other sized iterables. In addition,
it differs from the behavior of the ``collections.Mapping`` ABC --
