Just to clarify: Since elm-review is a static analysis tool separate from the compiler, you can run and compile your program just fine without having to handle all the dead code warnings (which elm-review is actually very good at detecting https://jfmengels.net/safe-dead-code-removal/).
I myself personally tend to run elm-review when I'm ready to make a PR most of the times.
