1.40 Fri 31 Jul 2009 - Dear Ruby Community. Thank you so much for your bug report to the "Ruby Talk" mailing list regarding the lack of true/false support in Perl YAML modules. http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/169943 This flaw has now been resolved, around 2 hours after we were made aware of it. Next time, we recommend you report these bugs to the people who can actually fix your problem, and they should be resolved in hours instead of 4 years.
