Sorry to resurrect an old-ish thread; I haven't looked at Python-dev in several weeks. I just wanted to point out that while everyone on this thread pointed out how this isn't a bug (clear to anyone who's spent enough time with Python), we have here an experienced C/C++ developer who is interested in helping out on Python core devel, and no one took him up on that offer. Jus, for what it's worth, there are a slew of *actual* Python bugs to be worked on--many languishing for years--due to lack of available developer time. You can have a good look at the (daunting) list of bugs at the old bugs.python.org [1]. IIUC Python development is slowly moving over to GitHub, but the issue list hasn't migrated yet so that would still be the place to start. If you find a bug that looks worth your time to try to fix, you should probably follow up on the issue for that bug itself. I can't make any promises anyone will have time for mentorship, but I'd be willing to point you in the right direction. I'm not a core developer but I know Python internals reasonably well and might be able to help *depending* on the issue.
