Issue #12515 has been updated by Daniel Berger. This was brought up in the past a lot: http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/96321 http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/186881 There's also this: http://stackoverflow.com/questions/3192978/why-does-ruby-have-trueclass-and-falseclass-instead-of-a-single-boolean-class ---------------------------------------- Feature #12515: Create "Boolean" superclass of TrueClass / FalseClass https://bugs.ruby-lang.org/issues/12515#change-59318 * 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: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
