What reason is there for this when the compiler could just optimize that variable out of existence? This feels like the most hand holdy annoying "feature" unless I'm missing something.
Cleaner code. That's all.
If you need to take variable you don't use for some reason (like it's a function arg that has to follow an interface, but it doesn't need a specific parameter in this case), then you can prefix it with an underscore.
That's what warnings are for and
-werrorfor production builds in literally any other language. This has been a solved problem for a very long time.Sure. Tell that to the Go devs.
If the language weren't pushed by Google, nobody would pay it any attention. It's yet another attempt to "do C right" and it makes some odd choices in the attempt.
...you don't accept them. Basically every programming language accepts some kind of
-werrorflag to turn warnings into errors. Warnings for development builds, errors for production builds. This has been a solved problem for a very long time. Not only is it assinine to force them to be errors always, it's semantically incorrect. Errors should be things that prevent the code from functioning in some capacity.It's a pretty standard flag in basically all compiled languages, just goes by a different name.
