Some notes: "CWE-563: Assignment to Variable without Use": https://cwe.mitre.org/data/definitions/563.html PVS-Studio implements this as V-519: https://pvs-studio.com/en/docs/warnings/v519/ https://pvs-studio.com/en/blog/examples/v519/ (lots of examples at that link) I'm not sure how well this ties into what the analyzer is already doing, though.
