I am thinking about [python-wart] on SO. There is no currently a list of Python warts, and building a better language is impossible without a clear visibility of warts in current implementations. Why Roundup doesn't work ATM. - warts are lost among other "won't fix" and "works for me" issues - no way to edit description to make it more clear - no voting/stars to percieve how important is this issue - no comment/noise filtering and the most valuable - there is no query to list warts sorted by popularity to explore other time-consuming areas of Python you are not aware of, but which can popup one day SO at least allows: + voting + community wiki edits + useful comment upvoting + sorted lists + user editable tags (adding new warts is easy) This post is a result of facing with numerous locals/settrace/exec issues that are closed on tracker. I also have my own list of other issues (logging/subprocess) at GC project, which I might be unable to maintain in future. There is also some undocumented stuff (subprocess deadlocks) that I'm investigating, but don't have time for a write-up. So I'd rather move this somewhere where it could be updated. -- anatoly t.
