alt Hacker NewsPython and C are the only language in which I have experienced that class of bugs. And that is due to if statements without brackets in C and because Python has meaningful indentation which people have accidentally messed up when refactoring.
And today with autofotnatters I think only Python is still vulnerable.
If you are messing up indentation accidentally during refactoring there is either something wrong with your tooling (including your text editor) or you are letting things get too far out of hand before starting the refactoring.
