(This is off-topic for the rails list).

IMO, subclassing Hash like this isn''t a good idea. Hash has too many
methods to get intermixed with your "open" methods.
Why not just expose the internal hash that OpenStruct uses:

  class OpenStruct
    attr_reader :table
  end

Then you can iterate over myobj.table
