Code to create a hash that lets you declare one key to reference another, used to answer this ruby-talk post.
Adding this mostly because I really enjoyed refactoring it. Compare the before version, which requires lots of comments to explain, and has complicated nested conditionals, and the after version, where any comments would be redundant. Might turn that into an assignment for Ruby Kickstart or something.
This code is unmaintained.
If you do something interesting with it, let me know so I can be happy.
