I did a search for "marshal" on ruby-talk.  This might be useful: 

http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/4570

Is there an article anywhere on advanced use of Marshal?  _Programming
Ruby_ only describes the most elementary case.  It would be nice to
see an explanation of eg. proper use of the depth argument (why is it
needed, when is it needed, how to use it).
