Bug #4471: sample list.rb generates warnings

ruby -v: ruby 1.9.3dev (2011-03-05 trunk 31026) [x86_64-darwin10.6.0] 


Running the file sample/list.rb using ruby -W2 generates warnings. I think sample code should not generate warnings, because samples should be examples of good code, not examples of bad code.

I don't mind if it's fixed by improving the script, or by deleting the script.
