ruby-dev #49961
Issue #13067 has been updated by Yukihiro Matsumoto. Status changed from Open to Closed Compatibility issue was bigger than I expected. I withdraw this proposal. Matz. ---------------------------------------- Feature #13067: TrueClass,FalseClass to provide `===` to match truthy/falsy values. https://bugs.ruby-lang.org/issues/13067#change-62575 * Author: Yukihiro Matsumoto * Status: Closed * Priority: Normal * Assignee: Yukihiro Matsumoto * Target version: ---------------------------------------- I propose to make `TrueClass`, `FalseClass` to provide `===` method to match truthy values (`TrueClass`), and falsy values (`FalseClass`), so that we can use true and false for case pattern matching. And we can pick truthy values using `grep` e.g. `ary.grep(true)`. Matz. -- https://bugs.ruby-lang.org/
