A quick "find all references" will point out it's not used and can be deleted if it accidentally gets checked in but ideally, you have systems in place to not let it get checked into the main branch in the first place.
Yeah that should be looked for in a CI line check, not a compilation requirement
You mean a system like the compiler
Or a linter. Or code reviews. Or anything else. The nice thing is that if the compiler doesn't demand something, it can be given to the engineer as an option. The compiler should have the option to do it. The option could even be defaulted on. Afaik there is no way in Golang to disable that error (this is the line that does it: https://github.com/golang/go/blob/04fb929a5b7991ed0945d05ab8015c1721958d82/src/go/types/stmt.go#L67-L69). like --no-pedantics or such. Golang's compiler openly refuses to give engineers more choices in what they think is the best system to handle it.
Who needs an option to leave unused variables around the code base? Lazybones?
You've literally never commented out a line or two but left the variable declaration while debugging?
Yeah any compiler should support environments or config files. Our CI would never work with without
--env “stage”
