Why not use an OpenStruct?

Because I'm an idiot :) - thanks!

Although there is one good reason - I want hash values to return another config object, so I can do:

Rails.config.github.another.anotherone

See https://github.com/rails/rails/blob/master/activesupport/lib/active_support/ordered_options.rb, which is what the Rails config uses.

@bkeepers - awesome, thanks - I've updated it to use that.
