(RSS) An unfocused collection of blog posts about Python, from tutorials for questions that come up over and over on StackOverflow to explorations of the CPython internals.
The blog originally started purely to talk about suggestions for improving the language (and still has a lot of that). Because Python is so mature and well designed, most ideas to improve it are bad ideas, hence the name.
In three separate discussions on the Python mailing lists this month, people have objected to some design because it leaks something into the enclosing scope. But "leaks into the enclosing scope" isn't a real problem.
