As your future colleague wondering what the hell that variable is for, thanks Go.
If only there was some way the compiler could detect unused variable declarations, and may be emit some sort of "warning", which would be sort of like an "error", but wouldn't cause the build to fail, and could be treated as an error in CI pipelines
Some people simply ignore warnings, that's the main issue. Trust me, I saw this way too often.
If you cannot compile it than you have to fix it, otherwise just mark unused variables as 'not an error' via
_ = someunusedvar.
