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:
