Python’s loop scoping is misdesigned, resulting in a very common gotcha for functions that close over loop variables [1]. The general problem is so bad that even the Go developers plan to break compatibility in order to fix the same design mistake in their language [2]. Enable the Ruff rule function-uses-loop-variable (B023) [3], which conservatively prohibits functions from binding loop variables at all.
