The warning was first meant to be introduced on Elixir v1.3 but we have delayed it because we had other warnings introduced in that version, such as the xref ones, and we wanted to call attention to those.
On this version we have focused mainly on the variable warnings because we understand they may be too frequent in some projects and also to avoid distracting from more important ones, as you said. Given Mix only compiles the files you changed, after the initial compilation, you should be able to tackle warnings gradually. If there are other warnings on this release besides the variable one that you believe are getting in the way, we will gladly hold them for another version so everyone is able to take their time to work on their projects. I don't want to make warnings optional. As a consequence, we are trying hard to not overload your projects with warnings on new versions. If that's happening, we are glad to discuss better strategies (for example, we can initially emit warnings only for variables inside functions) but overall the warning is not going away. *José Valim* www.plataformatec.com.br Skype: jv.ptec Founder and Director of R&D On Sat, Dec 3, 2016 at 7:32 PM, Steve Pallen <[email protected]> wrote: > I'm dead against this warning.
