You failed here. https://github.com/search?l=ruby&q=%22class Boolean%22&type=Code https://rubygems.org/search?query=Boolean I guess it's too late. ---------------------------------------- Feature #12515: Create "Boolean" superclass of TrueClass / FalseClass https://bugs.ruby-lang.org/issues/12515#change-59313 * Author: Loren Segal * Status: Open * Priority: Normal * Assignee: ---------------------------------------- Since Ruby 2.4 is unifying Bignum/Fixnum into Integer (https://bugs.ruby-lang.org/issues/12005), it seems reasonable to do something similar for TrueClass / FalseClass, and create a proper Boolean hierarchy. The implementation would be fairly straightforward and should be back compat unless someone already has a "Boolean" class at toplevel out there. Given the compatibility implications of Integer, this Boolean proposal is even less intrusive. Sample implementation: ~~~ class Boolean < BasicObject; end class TrueClass < Boolean; end class FalseClass < Boolean; end ~~~ -- https://bugs.ruby-lang.org/ Unsubscribe:
