So, I know two ways to do something like the following:

class Contrived
  @@examples = {}

  def self.create_example_accessor(name)
     class_eval <<-EOM
       def #{name}()
         return @@examples[#{name}]
       end
     EOM
  end

  def self.relink_example_accessor(name)
    alias_method(:name, :_example_accessor)
  end

  def _example_accessor
    me =  /:in `([^']*)/.match(caller(0).first)
    return @@examples[me]
  end
end

I sort of like relink_example_accessor for giving better backtraces and just
generally not being evaluating a string.  I'd like to have something cleaner
than either, just in general, and I'd like to also have a better
understanding of the pros and cons on each.
