Issue #17099 has been updated by S_H_ (Shun Hiraoka). Anyone has opinion? ---------------------------------------- Feature #17099: Remove boolean argument and warning from Module#attr https://bugs.ruby-lang.org/issues/17099#change-87285 * Author: S_H_ (Shun Hiraoka) * Status: Open * Priority: Normal ---------------------------------------- `Module#attr` works as `Module#attr_reader` by default (since in 1.9.1). Its optional boolean argument is obsoleted, but it works as `Module#attr_writer` when its value is `true`. I think it's okay to remove the optional boolean argument and the warning from `Module#attr`. pull request: https://github.com/ruby/ruby/pull/3386 -- https://bugs.ruby-lang.org/
