Ruby: Hash to Class

How to convert hash to class, to easily use it on views (i.e. in widgets, etc.)? Here's my solution:

class MacHash
  attr_accessor :hash

  def initialize hash
    self.hash = hash.symbolize_keys
  end

  def method_missing(method, *args)
    new_hash = hash[method]
    new_hash.is_a?(Hash) ? MacHash.new(new_hash) : new_hash
  end
end

And now we can test it:

hc = HashClass.new({:a => {:b => 10}, :c => [1, 2, 3]})

hc.a.b
=> 10

hc.c
=> [1, 2, 3]
