Issue #13067 has been updated by Robert A. Heiler. \o/ ---------------------------------------- Feature #13067: TrueClass,FalseClass to provide `===` to match truthy/falsy values. https://bugs.ruby-lang.org/issues/13067#change-62287 * Author: Yukihiro Matsumoto * Status: Open * Priority: Normal * Assignee: * 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/
