From: Trans Date: 2008-09-01T23:53:05+09:00 Subject: Core Date or no Date? Is there a core Date class or not? $ irb >>Date => Date >> Date.instance_methods(false) => [] >> Date.methods(false) => [] >> Date.private_instance_methods(false) => [] Huh? And the only documentation I can find is on the 'date.rb' standard library. T. P.S. Why can't ri isolate core from everything else?
