别再写类了

Jack Diederich's PyCon 2012 talk argues that classes are overused in Python and walks through real code, refactoring away unnecessary classes, exceptions and modules. It popularized the heuristic that a class with two methods, one being __init__, should be a function.

Why HN likes it: HN returns to it repeatedly as the canonical argument for simplicity and against premature abstraction, and several commenters say it changed how they write code.

“Jack Diederich has a great video called Stop Writing Classes: It's about Python, but the observation can apply to several languages.”
