Subject: Re: [QUIZ][SOLUTION] Hash to OpenStruct (#81)

Gotta post this before I look at other solutions.  This caused me to  
look up what an OpenStruct was so that was benefit #1.  Since it was  
a simple one, I worked through it with my son who is going through  
Chris Pine's _Learning_to_Program_ right now so that was benefit #2.

I don't know if this will handle the crazier recursive YAML files,  
but it seems to be fine for normal ones.  My son actually struck on  
the OpenStruct#send being a problem with the presence of the 'send'  
key in the YAML.

# RubyQuiz81: Hash to OpenStruct

require 'ostruct'
require 'yaml'

class HashToOpenStruct
   def self.from_yaml(yamlfile)
     self.to_ostruct(YAML.load(File.open(yamlfile)))
   end

   def self.to_ostruct(h)
     c = OpenStruct.new
     h.each { |k,v| c.__send__("#{k}=".to_sym,
                               v.kind_of?(Hash) ? to_ostruct(v) : v) }
     c
   end
end
