From: "byroot (Jean Boussier)" Date: 2022-07-29T17:58:47+00:00 Subject: [ruby-core:109375] [Ruby master Feature#18930] Officially deprecate class variables Issue #18930 has been updated by byroot (Jean Boussier). > the last time I tried something like that it was rejected: #14541. #14541 proposed to change their semantic, which is a hard proposition for backward compatibility. What I'm alluding to would be to introduce another syntax for true class variables, e.g `@$var` or something like that. That being said I don't want to derail this thread, I think it's a totally orthogonal proposition. ---------------------------------------- Feature #18930: Officially deprecate class variables https://bugs.ruby-lang.org/issues/18930#change-98524 * Author: Eregon (Benoit Daloze) * Status: Open * Priority: Normal ---------------------------------------- Ruby's class variables are very confusing, and it seem many people agree they should be avoided (#18927). How about we deprecate them officially? Concretely: * Mention in the documentation that class variables are deprecated and should be avoided/should not be used. * Add a parse-time deprecation warning, now that we only see those with `Warning[:deprecation] = true` it seems reasonable to add. -- https://bugs.ruby-lang.org/ Unsubscribe:
