Rails - Apr 2005 - Preloading reference data

Here''s my first little attempt at Ruby metaprogramming. It''s
an
extension of ActiveRecord::Base to allow for preloading reference data 
that is not changed (at least not while the app is running)

module ActiveRecord
  class Base
    def self.preload
      cattr_reader :all
      class_eval("@@all = self.find(:all)")
    end
  end
end

class Something < ActiveRecord::Base
  preload
end

Then, in a controller, say, you can access the preloaded instances as 
Something.all().

As always, I appreciate your comments.
