Perhaps also the tooling because any remotely decent IDE should show an error there, let alone the potential warnings of some code analysis software.

(This is one thing that baffles me about the “let’s use LLMs to code” movement; a lot of the proponents don’t seem to be just adding it as a tool (I don’t think it’s a terribly _useful_ tool, but whatever, tastes differ), but using it as the only tool, discarding 50 years worth of progress.)
